CCSS.6.EE.B.6

A term that has a set, specific value (aka… a number by itself) (in bold)  ex. 4x + 5

• variable

• constant

• coefficient

• operation

Check off ALL the coefficients from the following expression $-5x^3+x^2–\ 3x$  Be careful with signs, remember that we think of all terms being separated by + signs.  So subtraction would mean the coefficient is really adding a negative. Coefficients may be assumed, but not be written!

• -5

• 1

• 3

• -3
