Step-by-step explanation:
a = 1, b = 9, c = 8
with the quadratic formula;
x = -9 + \|9² - 4(1 × 8) ÷ 2(1) or x = -9 - \|9² - 4(1 × 8) ÷ 2(1)
x = -9 + \| 81 - 32 ÷ 2 or x = -9 - \| 81 - 32 ÷ 2
x = -9 + \| 49 ÷ 2 or x = -9 - \| 49 ÷ 2
x = -9 + 7 ÷ 2 or x = -9 - 7 ÷ 2
x = -2 ÷ 2 or x = -16 ÷ 2
x = -1 or x = -8
