With this question, we use the quadratic formula.

x = (-b±√b^{2}- 4ac)/2a

(-7±√7^{2 }- 4x-6x6)/2x-6

(-7±√49 - -144)/-12

(-7±√193)/-12

(-7 + 13.89)/-12 and (-7 - 13.89)/-12

-0.57 and 1.74

The answer is (-0.57, 1.74)

Woodland Hills, CA

This is Quadratic:

Use Quadratic formula:

f(X ) = - 6 X^2 + 7X +6

X = -b/2a ±√( -b/2) ^2 - 4ac) /2a

X = -7 / -( -12) ± (√[ (-7/12) ^2 - 4 ( -4) ( 4)/-12 ] =

= 7/12 ±√(7^2 +144)/12

= ( -0.57, 1.74)
