Question

x^2- (x + 2) (x + 2)/x + 3 = 1/2​

Answer 1

Answer:

$\frac{x {}^{2} - (x + 2)(x - 2) }{x + 3} = \frac{1}{2} \\ \\ \frac{x {}^{2} - (x {}^{2} - 4) }{x + 3} = \frac{1}{2} \\ \\ \frac{x {}^{2} - x {}^{2} + 4}{x + 3} = \frac{1}{2} \\ \\ \frac{4}{x + 3} = \frac{1}{2} \\ \\ 8 = x + 3 \\ 5 = x$

Step-by-step explanation:

(x+2)(x-2) is in the form of (a+b)(a-b)

$(a + b)(a - b) = a {}^{2} - b {}^{2}$

(x+2)(x-2) = x^2 - 4

nothing but x square minus four.
