well i need to simplify this problems out and i cant do it so here is one 3x^2+6x-45 ------------ = 3x^2+21x+30 Hi, First you should factor the numerator and denominator separately and then see if there is any cancellation. First the numerator, ^{ 2} + 6x - 45 = 3(x^{ 2} + 2x - 15)
= 3(x + 5)(x - 3)

Putting the numerator and denominator together I get Penny To return to the previous page use your browser's back button. |
