x2 + 24x +180 = 0 By using the quadratic equation, you can find that x = -12 + 6i or x = -12 - 6i
X=-3
(x - 6)(x - 2)
36. 02 = 0 62 = 36
It is: 3x2+6x-11 = 0
12 squared plus 18 squared is equal to 468.

5x2+7x = 12 5x2+7x-12 = 0 (5x+12)(x-1) = 0 x = -12/5 or x = 1
Answer : 12
It's a quadratic expression: x²+13x+12 If, for example, x²+13x+12 = 0 then there are 2 roots, x=-1 and x=-12
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
X = √63
It is: 3x2+6x-11 = 0
