Answer:
Step-by-step explanation:
The correct answer is D) x = 4 and x = -1
In order to solve this, we plug into the quadratic equation.
x =
In this case, a is the coefficient of x^2 (-1), b is the coefficient of x (3) and c is the constant (4). Now we plug in and solve.
x =
x =
x =
x =
And then we'll split into the two possible answers.
(-3 + -5)/-2 = -8/-2 = 4
(-3 - -5)/-2 = 2/-2 = -1
