Question

Simplify this expression: 7x^2+35x+28/2x^2+13x+20

Answer 1

21x^2+48x+20

Answer 2

7x^2+35x+28

Answer 3

If it's written like this

7x^2+35+28
_____________ < indicating division of the polynomials
2x^2+13x+20

then you have to factor both of them
the top factors to (7x+7)(x+4)
but from what I know the bottom one is unfactorable..

Answer 4

thanks

Answer 5

Sorry, the bottom one does factor I just had to try a little more :)
(2x+5)(x+4)

Answer 6

so your answer would be after cancelling (x+4)

(7x+7)
______
(2x+5)
