LEARNING TARGET
I can combine terms with the same variable part.
01 · LEARN
Build the idea
Terms with the same variable part count the same kind of object. Add their coefficients. Keep constants separate from variable terms and distribute before combining when parentheses are present.
Simplify 8(x + 3) + 2x. Explain which terms combine.
10x + 24
Add coefficients of x terms; add only constants to constants. Distribute first if needed.
