Answer:
option c
Step-by-step explanation:
2x² - 4x = 3
2x² - 4x - 3 = 0
a = 2, b = - 4, c = -3
[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \\\\x = \frac{4 \pm \sqrt{16 + 24 }}{4} \\\\x = \frac{4 \pm \sqrt{40}}{4} \\\\x = \frac{4 \pm \sqrt{4 \times 10} }{4} \\\\x = \frac{4 \pm 2\sqrt{10} }{4} \\\\x = 1 \pm \frac{\sqrt{10}}{2}[/tex]
