ACT SAT Prep Learn how to apply zero product property

The video tutorial explains the zero product property, emphasizing its importance in solving equations. It describes how if the product of two numbers or expressions is zero, then at least one of them must be zero. The tutorial provides examples to illustrate this concept and demonstrates how to solve equations using the zero product property. The session concludes with instructions for further practice.

What is the zero product property?

• If the sum of two numbers is zero, one of them must be zero.

• If the product of two numbers is zero, one of them must be zero.

• If the difference of two numbers is zero, one of them must be zero.

• If the quotient of two numbers is zero, one of them must be zero.

Why can't the product of 5 and 1/7 be zero?

• Because both 5 and 1/7 are zero.

• Because neither 5 nor 1/7 is zero.

• Because 1/7 is not zero.

• Because 5 is not zero.

What must be true for the product of two expressions to be zero?

• At least one of the expressions must be zero.

• Both expressions must be non-zero.

• The expressions must be different.

• The expressions must be equal.

What are the possible values of B in the equation B - 3 = 0 or B + 4 = 0?

• B = -3 or B = 4

• B = -3 or B = -4

• B = 3 or B = 4

• B = 3 or B = -4

Which value of B is the correct solution for the equation B - 3 = 0?

• B = -3

• B = 3

• B = 4

• B = -4
