Step-by-step explanation:
Given the quadratic equation;
x^2-5x-36=0
We have to look for two possible factors that may be added or subtracted to yield -5 and each must be a factor of 36.
The two possible factors now are -9 and +4
So we can write;
x^2- 9x + 4x - 36=0
x(x - 9) +4(x - 9)=0
Hence;
(x + 4) (x - 9) = 0
The two solutions of the equation are therefore;
x = -4 and x=9
