Which of the following methods would be the easiest to use to solve 2x2 + 4x – 3 = 0?
1 answer:
2x² + 4x - 3 = 0
x = <u>-(4) ± √((4)² - 4(2)(-3))</u>
2(2)
x = <u>-4 ± √(16 + 24)</u>
4
x = <u>-4 ± √(40)
</u> 4<u>
</u>x = <u>-4 ± 2√(10)
</u> 4<u>
</u>x = -1 ± ¹/₂√(10)
x = -1 + ¹/₂√(10) U x = -1 - ¹/₂√(10)
