Simplify the expression 
20120212 

From Christy: Hi guys, ok so I'm having problems with solving this equation since it's been so long I've done precal.
I have to find critical points so I have to find the derivative first. This is what I've done so far
s(t)= (t6)^4 * (t+1)^2
t'= 4(t6)^3*(1)*(t+1)^2+ 2(t+1)(1)*(t6)^4
so this is where I got stuck, which is the algebra part. How can I simplify this to get the answer to figure out the critical points. Answered by Penny Nom.

Simplifying a quadratic expression 
20091207 

From Sabbie: Hi, I need help solving this equation for my physics homework,so I can solve the quadratic equations for x and y.
I've derived the following equations from the information provided in the question.
2a+3b = 4  1
2a^2 + 3b^2 = 62  2
a=2(3/2)b is substituted into equation 2.
so, i get
2 (2(3/2)b)^2 + 3b^2 = 62
this is where the problem begins. i cannot work through this to get to the correct quadratic equation
5b^28b36=0
I can't seem to be able to figure out where I keep going wrong. I would really appreciate it if you could give me a stepbystep breakdown of the workout.
thanks! Answered by Penny Nom.
