Question

What are the solutions to the quadratic equation 2x2 - 8x- 24 = 0? O A. x= -6 and x = 4 O B. x= -4 and x = 6 O C. x = -2 and x = 6 O D. x= -3 and x = 8 SUBMIT

Answer 1

Answer is: x= 6 and x= -2 (C.)

Step-by-step explanation:

For a quadratic equation of the form ax^2 +bx +c = 0 the solutions are:

$x_{1,2}=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}$

For a=2, b=-8 and c=-24
