For each term, determine the coefficient of the term and the variable part of the term.
Coefficient is 2π, variable part is xy2.
Coefficient is 27, variable part is ab.
2x · 7z
Coefficient is 14, variable part is xz.
Are the following like terms?
3xyz and 4πxyz
Yes. Remember that π is a constant. A non-number does not always a variable make.
3xy2z and 5xyz2
No. First term has y2, second term has z2.
57 and 84
Yes. Neither term has a variable part.
Combine like terms.
3x + 3y - 4x + 2
- x + 3y + 2
4x - 7y + 3x2 - y
4x - 8y + 3x2
x - y + 2 - y
x - 2y + 2
