Find the solutions of the quadratic equation 6x^2-6x-2=0

Choose 1

(choice A)
A

(choice B)
B

(choice C)
C

(choice D)
D

Step-by-step explanation:

Divide both sides by 2.

We compare it to the standard form:

We have a = 3, b = -3, c = -1.

To factor, we need two numbers that multiply to ac and add to b.

ac = 3 * (-1) = -3

-3 = -3 * 1; -3 + 1 = -2

-3 = -1 * 3; -1 + 3 = 2

There are no two integers whose product is -3 and whose sum is -3, so we cannot factor the trinomial. We use the quadratic formula to solve the equation.
