Answer :
x² + 8x + 10 = 0
x = -(8) +/- √((8)² - 4(1)(10))
2(1)
x = -8 +/- √(64 - 40)
2
x = -8 +/- √(24)
2
x = -8 +/- 2√(6)
2
x = -4 + √(6)
x = 4 + √(6) x = 4 - √(6)
x = -(8) +/- √((8)² - 4(1)(10))
2(1)
x = -8 +/- √(64 - 40)
2
x = -8 +/- √(24)
2
x = -8 +/- 2√(6)
2
x = -4 + √(6)
x = 4 + √(6) x = 4 - √(6)
