		From zoe: what is so important about quadratics? Answered by Harley Weston.
	Using FOIL for (2x - 6)^2		2007-05-18
		From TONI: I am having a problem finding examples of how to solve (2x-6)^2. Answered by Stephen La Rocque.
	Quadratics		2005-01-05
		From Usman: Hi, in my Grade 11 Functions math class we have been assigned the task of finding jobs and careers related to quadratics, I have done many searches but have been unsuccessful, then I saw your website and e-mailed. I also have to use an example of a math problem that the job uses, then solve it, this will all compile on bristol board for a presentation. I would greatly appreciate it if you could send me some links and references of sources that refer to this subject. Answered by Harley Weston.
	Solving quadratics		2004-11-20
		From Aaron: Can you solve the following equation (quote the value of x,y and t to 3 sig figs) ((i have changed figures so that i can work through my own example)) x2 + x - 6 = 0 5y2 +19y = 3 10cos2 t + 3cos t = 4 Answered by Penny Nom.
	Factoring		2004-11-09
		From Rise: Q1: a2 + 5a + 6 I didn't really understand the purpose of the teacher's steps, but was able to get my daughter to find factors of 6 and then add them together to find which resulted in the sum of 5. Unfortunately, this problem-solving technique did not help us to solve for the more complex problems as follows: Q2: 9a3 - 24a2 + 12a Answered by Penny Nom.
	Factoring		2004-07-28
		From Nicole: Can 4x2 + 19x + 12 be factored? i have tried but i cannot figure it out. Is there a way to find out if it cannot be factored before i try to work out the problem? Answered by Penny Nom.
	Two intersecting graphs		2003-04-23
		From Patty: a) graph the equation x2 - y - 4 = 0 x2 + y2 = 9 on the same set of coordinate axes. I did not have a problem with this. The problem is part (b) of the question ask: Find all solutions of the system in part (a) algebraically. Express answers in decimal form, accurate to two decimal places. Answered by Penny Nom.
	Quadratics		2001-05-16
		From John: I am in the final stages of a math project and I need to interview an expert for the last part. Please try to answer at least a few of these questions. How do you use quadratic equations in your everyday life? Do you find being a math expert very helpful in life? Is the quadratic equation useful to you? Why did you decide to become a math expert? What do you think is the most important function of the quadratic equation? Answered by Harley Weston.
	The solutions of a quadratic		2001-01-30
		From A student: Show that the product of the solutions of ax2 + bx + c = 0 is c/a. For each equation under the given condition, (a) find k and (b) find the other solution. kx2 - 2x + k = 0; one solution is -3 Answered by Penny Nom.
	Two conics		1999-12-07
		From Quinn: I know the formula to find the axis of symmetry of a conic section (I'm not sure what shape - circle for the first one??) is (-D/2A,-E/2C) but I obviously don't get how to calculate it, because when I check the answer it's wrong, but I'm so close!! For the following equations my teacher suggested to "divide the x term coefficient, D, by the x squared term coefficient before...do the same for y." 2x2+2y2-8x+12y+16=0 . . . Answered by Penny Nom.
	Two Quadratics		1999-10-08
		From Jason On: Solve the following equations,expressing solutions in the form p + iq. sqr(x) + 2x - 1 = 0, sqr(x) + 2x - 3 = 0. Answered by Harley Weston.
	The Quadratic Formula		1999-01-22
		From Eric Morgan: Hi my name is Eric Morgan and I m in 8th Grade honors math (middle) and I'd like to know how to prove the quadratic formula -b±sqrt of b(a)(c)over 2(a) Answered by Penny Nom.
	Solving Quadratics		1998-07-16
		From Fred Goodrich: I need a step by step lesson on solving quadratic equations. Thank you, Answered by Penny Nom.
	Polynomials		1997-10-07
		From Sheryl and Jeff: I'm a math teacher in Jerusalem, Israel. I'm teaching about graphing polynomial functions in a pre-calc class. A student asked me what they're good for. I couldn't give her a good example. Do you have one. Thanks. Answered by Penny Nom.
