Use the quadratic formula, x=−b±b2−4ac√2a, to solve the equation −2x2−6x+3=0. Match each step to the correct method for solving the equation.

Step-by-step explanation:

We are given the equation:

And we want to solve it using the quadratic formula:

First, let's identify our coefficients.

The a is the coefficient in front of the x² term, so a = -2.

b is the coefficient in from of the x term, so b = -6.

And c is the constant so c = 3.

Substitute:

Simplify. -(-6) is just 6. (-6) squared is 36. -4(-2)(3) is 24. And 2(-2) is -4. So:

Add:

Simplify the square root:

So:

Simplify by dividing everything by 2:

Move the negative in the denominator to the numerator. The plus/minus sign will not change.

So, our zeros are:
