Which of the following could be the solution set to 8x² - 2x = 1? {-1/4, -1/2} {-1/4, 1/2} {1/4, 1/2}
8x² - 2x = 1 8x^2 - 2x - 1 = 0 (2x - 1)(4x + 1) = 0 x = 1/2 or x = -1/4 the solution set to 8x² - 2x = 1 is {-1/4, 1/2}

8x² - 2x = 1
8x^2 - 2x - 1 = 0
(2x - 1)(4x + 1) = 0
x = 1/2 or x = -1/4
the solution set to 8x² - 2x = 1 is {-1/4, 1/2}
