Expert Answer:

Factorize the following quadratic equation:


In order to factorize x2-23x+132, we have to find two numbers p and q such that p+q=-23 and pq=132.                                                                

Clearly, -12-11=-23 and -12 x -11=132.

We now split the middle term-23x of x2-23x + 132 so that

x2-23x+132 = x2-12x-11x+132
