Answer 2

Correct question:

Factorize the given quadratic polynomial ;

x² - 13x - 114 .

Answer:

(x - 19)(x + 6)

Solution:

Here,

The given polynomial is ;

x² - 13x - 114 .

We need to factorize the given polynomial .

Let's factorize it by middle term splitting method.

Working rule :

Split the middle term in such a way that the product of its parts is equal to the product of first and last term .

Now,

=> x² - 13x - 114

=> x² - 19x + 6x - 114

=> x(x - 19) + 6(x - 19)

=> (x - 19)(x + 6)

Hence,

The required answer is :

(x - 19)(x + 6)
