Using The Quadratic Formula

Identify the values of a, b, and c

10p² + 7p - 20 = 0

• a=1, b=7, c=-20

• a=10, b=7, c=20

• a=10, b=-7, c=-20

• a=10, b=7, c=-20

Identify the values of a, b, and c

3m² - 14 = 11m

• a=3, b=-11, c=-14

• a=3, b=-14, c=11

• a=3, b=11, c=-14

• a=3, b=-14, c=11

Identify the values of a, b, and c

5x² + x - 18 = - 9x + 3x²

• a=2, b=10, c=-18

• a=5, b=1, c=-18

• a=8, b=-8, c=-18

• a=2, b=9, c=-18

What is this formula?

• This is the speed of light formula.

• This is the quadratic formula.

• This is the zero product property.

• This is scary.
