Solved Example on Zero - Product Property Solve: (x + 5)(x – 1) = 0 Choices: A. – 1, 5 B. 1, 5 C. – 5, - 1 D. 1, - 5 Correct Answer: D Solution: Step 1: (x + 5)(x – 1) = 0 [Given equation.] Step 2: x + 5 = 0 or x – 1 = 0 [Applying Zero-product property.] Step 3: x + 5 – 5 = 0 – 5 or x – 1 + 1 = 0 + 1 [Simplify the equations.] Step 4: x = - 5 or x = 1 Step 5: The solutions for the equation (x + 5)(x – 1) = 0 are 1 and – 5.

Solve: (x + 5)(x – 1) = 0 Choices: A. – 1, 5 B. 1, 5 C. – 5, - 1 D. 1, - 5 Correct Answer: D Solution: Step 1: (x + 5)(x – 1) = 0 [Given equation.] Step 2: x + 5 = 0 or x – 1 = 0 [Applying Zero-product property.] Step 3: x + 5 – 5 = 0 – 5 or x – 1 + 1 = 0 + 1 [Simplify the equations.] Step 4: x = - 5 or x = 1 Step 5: The solutions for the equation (x + 5)(x – 1) = 0 are 1 and – 5.

Solve:

(x + 5)(x – 1) = 0

Choices:

A. – 1, 5

B. 1, 5

C. – 5, - 1

D. 1, - 5

Correct Answer: D

Solution:

Step 1: (x + 5)(x – 1) = 0 [Given equation.]

Step 2: x + 5 = 0 or x – 1 = 0 [Applying Zero-product property.]

Step 3: x + 5 – 5 = 0 – 5 or x – 1 + 1 = 0 + 1 [Simplify the equations.]

Step 4: x = - 5 or x = 1

Step 5: The solutions for the equation (x + 5)(x – 1) = 0 are 1 and – 5.
