Question

Solve the quadratic equation: 2x2 + 11x − 6 = 0

Answer 1

ANSWERS:

Answer 2

use the super quadratic formula. let a=2,b=11, and c=-6

Answer 3

2x^2 + 11x - 6 = 0
a = 2 b = 11 c = -6

quadratic formula:
x = -b +/- sqrt b^2 - 4ac / 2a
x = -11 +/- sqrt 11^2 -4(2)(-6) / 2(2)
x = -11 +/- sqrt 121 + 48 / 4
x = -11 +/- sqrt 169 / 4
x = -11 +/- 13 / 4

So there you have your two equations which you'll need to do for your answer.

-11 + 13 / 4
2 / 4
1/2 is your first one

-11 - 13 / 4
-24/4
-6 is your second one

Answer 4

So your answer is the third.
