Solving Quadratics with Factoring, Square Root Property, Quadratic Formula

Solve using the Zero Product Property.

• b=4/5, b=3

• b=4, b=-3

• b=1/5, b=3

• b=4/5, b=-3

Solve the quadratic equation by factoring
a² + 10a + 21 = 0

• ± √21

• -3 , -7

• 3 , 7

• 28 , -7

What is this?

• This is the speed of light formula.

• This is the quadratic formula.

• This is the zero product property.

• This is scary.

Solve by factoring:

x² + 2x - 24 = 0

• x = -6, x = 4

• x = 6, x = -4

• x = 12, x = -2

• x = 8, x = -3

Solve x^2 - 3x - 4 = 0 using the quadratic formula.

• x = 4 and -1

• x = -4 and -1

• x = 4 and 1

• x = -4 and 1

Convert x² - 9x + 20 = 0 to factored form and solve.

• (x-10)(x+2)=0; x = -2, 10

• (x+4)(x+5)=0; x = -5, -4

• (x-4)(x-5)=0; x = 4, 5

• Not factorable
