Question

solve the following equation. Express any irrational solutions in simplest form.
(x^2+5x-7)(x+2)=0

Answer 1

you have an expression , that is a product of two terms, and it equals zero,

this implies that at least one of the terms Must be zero

Answer 2

so
(x^2+5x-7)=0 or (x+2)=0

Answer 3

I guess you have to factor them out but I am confused. This cannot be factored right ?

Answer 4

for the first term you'll have to use the quadratic formula

Answer 5

\[ax^2+bx+c=0\\
~\\
x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\]

Answer 6

ok thank you. I appreciate it.
