Answer :
2x² + 4x - 3 = 0
x = -(4) ± √((4)² - 4(2)(-3))
2(2)
x = -4 ± √(16 + 24)
4
x = -4 ± √(40)
4
x = -4 ± 2√(10)
4
x = -1 ± ¹/₂√(10)
x = -1 + ¹/₂√(10) U x = -1 - ¹/₂√(10)
x = -(4) ± √((4)² - 4(2)(-3))
2(2)
x = -4 ± √(16 + 24)
4
x = -4 ± √(40)
4
x = -4 ± 2√(10)
4
x = -1 ± ¹/₂√(10)
x = -1 + ¹/₂√(10) U x = -1 - ¹/₂√(10)
