Question

2x² - 2x - 24 = 0 what ????
​

Answer 1

Step-by-step explanation:

2x² + 2x - 24 = 0

A = 2

B = 2

C = -24

∆ = b² - 4.a.c

∆ = 2² - 4. 2. (-24)

∆ = 4 + 192

∆ = 196

X = - b ± ✓∆ / 2.a

X = -2 ± ✓196 / 4

X = -2 ± 14 / 4

X' = 12/4 = 3.

X" = -16/4 = -4

S: {3; -4}

$x=4\\x= -3$

Answer 2

FOR YOUR QUESTION THE ANSWER IS X = 4 OR X = -3
