• Quadratic Formula

• Factoring

You should only use the quadratic formula in two situations. First, if the instructions say to. Second, if you cannot factor.

• Got it!

• I wrote it down!

• Understood.

• (-8, 0) and (5, 0)

• (8, 0) and (-5, 0)

• (8, 0) and (5, 0)

• Answer not shown.

What does the quadratic formula do?

In the equation
y = x² +5x +7, match each leading coefficient with its correct letter 

• a=0, b=5, c=7
• a=1, b=5, c=7
• a=7, b=5, c=1
