Answer 1

Given:

• x² + 7x + 12

To do:

• Solve the equation by factorization method.

Solution:

⇒ x² + 7x + 12

According to factorization method, first we need to split the middle term. Here, 7x can be written as 4x + 3x [Sum - product pattern].

⇒ x² + 4x + 3x + 12

Let us take x and 3 as common factors from two pairs.

⇒ x(x + 4) + 3(x + 4)

Now, rewrite the equation in factored form.

⇒ (x + 3)(x + 4)

Hence, our equation is solved by factorization method.
