Question

solve 2x(x-1) + 2(3x-1) = 0​

Answer 1

Step-by-step explanation:

2x(x-1) + 2(3x-1) = 0

=》2x² - 2x + 6x -2 =0

=》2x² - 4x - 2 = 0

by using quadratic formula

D = b² - 4ac

=》 D = -4² - 4×2×-2

=》 D = 16 + 16

=》 D = 32

=》

$x = \frac{ - b \: + - \: { \sqrt{d} }^{2} }{2a}$

=》

$x = \frac{4 + \sqrt{32} }{4} \: or \: \frac{ 4 - \sqrt{32} }{4}$
