All equations of the form ax^ {2}+bx+c=0 can be solved using the quadratic formula: \frac {-b±\sqrt {b^ {2}-4ac}} {2a}. The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction. This equation is in standard form: ax^ {2}+bx+c=0.
To solve the equation, factor x^{2}+x-2 using formula x^{2}+\left(a+b\right)x+ab=\left(x+a\right)\left(x+b\right). To find a and b, set up a system to be solved. a=-1 b=2
