Problem 146 of 7
Solve the system using the factored quadratic form: y=2(x-3)(x+1), y=-8.
Using a hint is okay. It just tells the trainer to give you a little more review.

Quadratic must be supplied in factored form and paired with a linear equation.
Enter your answer
Your answer is equivalent to the expected form.

Full solution stays hidden until you ask for it.
1. Set the factored quadratic expression equal to the linear expression.
2. Simplify to a quadratic equation and solve.
3. Substitute each x-value into the line to find y.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Reporting factor zeros only when the line is not y=0.
