Answer 2

To solve this equation, we can start by expanding the left side using the identity:

(a + b)^2 = a^2 + 2ab + b^2

Using this identity, we get:

(2x + 1)^2 - (3 - 2x)^2 = 40 4x^2 + 4x + 1 - (9 - 12x + 4x^2) = 40 4x^2 + 4x + 1 - 9 + 12x - 4x^2 = 40 8x - 48 = 0

Simplifying the equation, we get:

8x = 48

Dividing both sides by 8, we get:

x = 6

Therefore, the solution to the equation is x = 6.
