Question

Can somebody tell me the steps for this ?

Answer 1

first factor it
then set each of the stuff inside each parenthesis equal to zero and solve for both.

Answer 2

So the function is :
f(x)=x^2+12x+20,
first we need to factor, that means find two numbers that multiply to 20, but add to 12
they are
10, and 2
and that's how you solve it. If they want it in the form:
(x-?)(x-?), then it will be :
(x-10)(x-2)
