To solve for x in the equation 8x^2 - 5 = 67, we first need to isolate the x^2 term.
Adding 5 to both sides gives:
8x^2 = 72
Divide both sides by 8 to solve for x^2:
x^2 = 9
Taking the square root of both sides gives two possible solutions for x:
x = ±3
Therefore, the solutions for x are x = 3 or x = -3.
