Question

help factoring this trinomial please?


x^2+4x-5=

Answer 1

Thats actually a bi-nomial....only has a power of 2

so x² + 4x - 5

you know you need x times x so

(x ) (x )

now we need the factors of 5

5 and 1 are the only 2 so

(x + 5) (x - 1)

to check...multiply it out

x² - 1x + 5x - 5
x² + 4x - 5
