Question

Show step-by-step how to factor \[\LARGE x^2+12x+36\]

Answer 1

Use quadratic formula if you can't factor.

Answer 2

But the answer is obviously x = - 6

Answer 3

there ya go

Answer 4

For factoring:
You need to think, what numbers ADDED make up 6 and MULTIPLIED give 36?

xy = 36
x + y = 12

if you want you could solve it like that ^ using a system of equations to find the factors.
but its obviously 6
so

\[\Huge (x+6)(x+6) = x^2 + 12x + 36\]
or simply
\[\Huge (x+6)^2 \]

Answer 5

added make up 12*
