Algebra 2 Solving Quadratics by Factoring or QuadraticDay 3

Solve for all values of x by factoring:

x² - 5x = 0

• x = 5 only

• x = 0 and x = 5

• x = 0 only

• x = 1 and x = 5

Solve for all values of x by factoring:

x² + 8x = 5x

• x = 8 and x = 5

• x = 0 and x = 3

• x = -8 and x = -5

• x = 0 and x = - 3

Solve for all values of x by factoring:

x² - 36 = 0

• x = 0 and x = 36

• x = 6 and x = 6

• x = 0 and x = - 36

• x = 6 and x = - 6

Solve for all values of x by factoring:

x² - 48 = 1

• x = 7 and x = -7

• x = 48 and x = 1

• x = 7 and x = 7

• x = -48 and x = - 1

Solve for all values of x by factoring:

x² - 3x - 10 = 0

• x = 3 and x = 10

• x = 5 and x = -2

• x = -5 and x = 2

• x = -3 and x = -10

Solve for all values of x by factoring:

x² - 10x + 30= 2x - 2

• x = 8 and x =4

• x = -8 and x =-4

• x = 12 and x = -32

• x = -12 and x = 32

Solve for all values of x by factoring:

5x² - x - 4 = -9x

• x = (2/5) and x = 2

• x = -8 and x =-4

• x = 8 and x = 4

• x = (2/5) and x = - 2

Solve for all values of x by factoring:

3x² + 17x = -3x + 7
