Question

Which of the following is a factor of x2 + 2x − 48

Answer 1

Factors of -48 that add up to 2

-6 and 8

So these are the factors (x + 8)(x - 6)

If you have any of those as th option, it is the answer.

Answer 2

Factors of x²+2x-48 are:

(x-6) and (x+8)

Explanation:

We have to factorize x²+2x-48

We will use the method of splitting the middle term where we factor the middle term i.e. coefficient of x into two factors

x²+2x-48 could also be written as:

x²+8x-6x-48

x(x+8)-6(x+8)

(x-6)(x+8)

Hence, factors of x²+2x-48 are:

(x-6) and (x+8)
