How to Determine The Zeros when a Polynomial is in Factored Form

The video tutorial covers the process of solving equations by factoring. Initially, students are reminded of the need to factor expressions, which serves as a remediation step. The instructor then presents problems that are already factored, allowing students to apply the zero product property. This involves setting each factor equal to zero and solving for the variable X. The tutorial concludes with solving specific equations, including taking square roots and handling negative solutions.

What is the first step when given a problem that is already factored?

• Set each factor equal to zero

• Divide each term by zero

• Multiply all terms together

• Add all terms together

When solving the equation X = 0, what is the value of X?

• 0

• 1

• 2

• -1

What must be done before subtracting one in an equation involving a square root?

• Add one to both sides

• Multiply both sides by two

• Take the square root

• Undo the square root

If X + 1 = 0, what is the value of X?

• 1

• -1

• 0

• 8

In the equation X - 8 = 0, what is the solution for X?

• 8

• 1

• 0

• -8
