Vocabulary:
In algebraic expressions & equations, like terms are terms
that contain the same variables raised to the same power.
Only the coefficients of like terms can be different.
1. Coefficient:
Examples include: 7x x -2x (
1
3
)xy2 -2y2x 6xy2
Adding & Subtracting like terms is just combining the coefficients.
2x2 + 5x =
