(x^2+10x+25)/(x^2+9x+20)

Answer 1

factor the numerator and denominator

\[\frac{(x +5)(x+5)}{(x+4)(x+5)}\]

now just remove the common factor

Answer 2

I'm confused about the 9x, how is that factored?

Answer 3

This simplified is (5+5)/(9+2)

well what are the factors of 20 that add to 9....

4 + 5 and 4 x 5

thats how you can factor the numerator to

(x +4)(x + 5)

Answer 5
