Answer:
(5x+1)(x+7)
Step-by-step explanation:
4x^2+26x+6+x^2+10x
5x^2+36x+7
(5x+1)(x+7)
Prove
5x*x + 5x*7 + 1*x + 1*7
= 5x^2 + 35x + x + 7
= 5x^2 + 36x + 7
We want to simplify:
first we factorize
as
then multiply
by
to equalize the denominators of the first expression, and add the fractions.
simplify x+3:
a.
b.
steps already described
c.
x cannot be -1, nor -3 because the fractions with denominators (x+1) and (x+3) would not be defined.
