In the given polynomial p²+p−132,

The first term is p² and its coefficient is 1.

The middle term is p and its coefficient is 1.

The last term is a constant term −132.

Multiply the coefficient of the first term by the constant 1×−132=−132.

We now find the factor of −132 whose sum equals the coefficient of the middle term, which is 1 and then factorize the polynomial p²+p−132 as shown below:

p²+p−132=p²+12p−11p−132=p(p+12)−11(p+12)=(p−11)(p+12)

Hence, p²+p−132=(p−11)(p+12).
