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.

What is 12 squared plus 18 squared?
12 squared plus 18 squared is equal to 468.
What is A squared plus 6 squared equals 12 squared?
a2 + 62 = 122 a2 + 62 - 62 = 122 - 62 a2 = 144 - 36 a2 = 108 taking the square root of each side, we get a equal plus or minus the square root of 108, or plus or minus 6 times the square root of 3.
What is the discontinuity of the function f(x) the quantity of x squared minus 4 x minus 12 all over x plus 2?
In such cases, there is usually a discontinuity when the denominator is zero. In other words, solve for:x + 2 = 0
How do you factor the expression x squared plus 1x minus 12?
The expression x2 + 1x - 12 can be factored out as (x - 3)(x + 4)
Simplify p squared minus 3p over p squared minus 6p plus 9 divided by 20 over 4p-12?
answer is p/5. problem: {[(p^2)-3p]/[(p^2)-6p+9]}/{20/(4p-12)}
What is 12 squared minus 17 plus 6?
133
How do you factor x squared plus 9x minus 36?
(x + 12)(x - 3)
What is the factor to x squared plus 7x minus 60?
(x - 5)(x + 12)
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'.
What is x in the equation -3x squared minus 5x plus 12 equals 0?
X=-3
What is minus 2 squared minus 12?
-22 - 12 = -8
Solve the equation 15x minus 12 equals 3x plus 8?
15x minus 8=minus 180 3x+8=24
What is 12 squared plus 18 squared?
12 squared plus 18 squared is equal to 468.
How do ypu factor X squared minus 13x plus 12?
It is x^2 -13x +12 = (x-1)(x-12) when factored
How do you factor 36 x squared minus 12 x plus 1?
(6x - 1)(6x - 1)
What is negative four plus three x minus two x squared -4 plus 3x-2x squared?
Let square = [x] -4+3*(-2)*[-4]+[3x-2x]=-4-6-2+[x]=-12+[x]The answer is negative 12 plus squared x.
What is A squared plus 6 squared equals 12 squared?
a2 + 62 = 122 a2 + 62 - 62 = 122 - 62 a2 = 144 - 36 a2 = 108 taking the square root of each side, we get a equal plus or minus the square root of 108, or plus or minus 6 times the square root of 3.
