• 7, -7

• only 7

• No solutions

• One solution

• Two solutions

• Infinitely many solutions

Match each quadratic equation with the type of solutions it would have if you solved it for x.

• Complex solution (non-real)

• One rational solution

• Two rational solutions

• Two irrational solutions

Solve for x

(x - 1)² = 49

Only type numbers! Include a comma if more than one answer!

Use the quadratic formula to find the solutions for

y = -x² - 5x + 12

The x-intercepts of a quadratic function are x = -1 and x = 5. Which could the be the equation of the quadratic function?
