Question

Solve for x. 8x^2-3=2

Answer 1

$(2^3x^2 - 3) - 2 = 0 \\ \\ Factoring: \ 8x^2-5 \\ \\ 8x^2 - 5 = 0 \\ \\ Add \ 5 \ to \ both \ sides \ of \ the \ equation : \\ \\ 8x^2 = 5 \\ \\ Divide \ both \ sides \ of \ the \ equation \ by \ 8: \\ \\ x^2 = \frac{5}{8} = 0.625 \\ \\ \boxed{ x =\pm \sqrt 5/8}$
