Guided Practice for Solving Equations

Solve for the values of x:
(x + 2)(x - 3) = 0

• { 2, 3 }

• { -2, -3 }

• { 2, -3 }

• { -2, 3 }

Solve and find your zeros: z(z - 15)=0

• z = 0 and z = 15

• z = 0 and z = -15

• z = 0 only

• z = 15 only

• z = -15 only

Solve for x: (2x-1)(x+4)=0

• -4

• 2

• -2

• 4
