Who can help solve this problem? Solve the equation 5x ^ 2 + x = 2 + X √ (5x ^ 2-1)

5x ^ 2 + x = 2 + X √ (5x ^ 2-1) 5x ^ 2-x √ (5x ^ 2-1) = 2-x (5x ^ 2-1) - x √ (5x ^ 2-1) = 1 - x (5x ^ 2-1) - x √ (5x ^ 2-1) + x ^ 2 / 4 = x ^ 2 / 4 - x + 1 {radical (5x ^ 2-1) - X / 2} ^ 2 = (x / 2 - 1) ^ 2 radical (5x ^ 2-1) = x / 2 ± (x / 2 - 1) = x - 1, or 1 (one
