Answer 2

Given equation:

• [{(2x + 2)(x + 3)} + 8] = (2x + 1) (x + 5).

To find:

• The value of x?

Solution:

Here in this question, we are provided with a equation and we are asked to solve that equation to find the value of x, let's start solving our equation and understanding the steps to get our value of x.

→ [{(2x + 2)(x + 3)} + 8] = (2x + 1) (x + 5)

→ (2x + 2)(x + 3) + 8 = (2x + 1)(x + 5)

→ 2x² + 8x + 6 + 8 = (2x + 1)(x + 5)

→ 2x² + 8x + 14 = (2x + 1)(x + 5)

→ 2x² + 8x + 14 = 2x² + 11x + 5

→ 2x² - 2x² + 8x + 14 = 11x + 5

→ 8x + 14 = 11x + 5

→ 8x - 11x = 5 - 14

→ -3x = 5 - 14

→ -3x = -9

→ 3x = 9

→ x = 3.

Hence,

• The value of x option (b) 3.
