AVA High School
Algebra 1
Mr. Daigre

​Georgia Standards of Excellence

​MGSE9-12.A.SSE.2 - Use the structure of an expression to rewrite it in different equivalent forms

How does prime factorization help us factor trinomials?

Lesson Question

​Learning Target

- ​I can factor expressions using the trinomial method

Warm Up Example:

x² + 8x + 16

Vocabulary

• trinomial - an algebraic expression that has three terms in it

• term - a constant, a variable, or a variable and its coefficient

• factored form - an expressions that has been fully factored

Trinomial Method

How can we break down a trinomial?

• What 2 numbers add together to each the middle number, and multiply together to equal the last number?

​x² + 5x + 6

Trinomial Method

How can we break down a trinomial?

• Group the split trinomial into two halves with parentheses and factor the halves

​x² + 5x + 6

Trinomial Method

How can we break down a trinomial?

• Rearrange the expression into its factored form

​x² + 5x + 6

Multiple Choice

Factor the following expression:

x²+ 10x + 16

• (x - 2)(x - 8)

• (x + 2)(x + 8)

• 8 (x+2)²

• (x +10)(x +16)

Multiple Choice

Factor the following expression:

d²+ 7d + 12

• (d + 2)(d + 6)

• (d + 4)(d - 3)

• (3d + 4)²

• (d + 4)(d + 3)

Instructions: Go to your Zoom breakout room, and pick 2 problems in the Jamboard to work out with your group members. The problems must be from 2 different levels. I will be going from group to group assisting as needed.
