You need to factor it.
- Set it equal to zero
x2+x-12=0
- Find what adds up to equal 1 and multiplies together to equal 12, because 1 is the constant for the B and the constants for A and C multiply together to equal 12. Take these two numbers plus x and multiply them.
(x+4)(x-3)=0
- One of these factors needs to be zero to make the statement equal to zero so set them both equal to zero.
x+4=0, x-3=0
- Solve to find the two solutions for x.
x=-4, x=3
You can also use the quadratic formula, but factoring is easier when it's possible.

How do you solve this z squared minus 12 plus 36?
z2 - 12 + 36 is the same as z2 + 24. That's a simplification, but not a solution. There's nothing to solve, because the question doesn't give an equation. If z2+24 were equal to something, then we'd have an equation, and we would be thrilled to solve it for the value of 'z'.
