Work Step by Step

We write an expression to express this subtraction problem: $(8x^2-2x+6)-(2x^2+6x-1)$ We use the commutative, associative, and distributive properties to group like terms: $(8-2)x^2+(-2-6)x+(6-(-1))$ We combine the like terms within each set of parentheses: $6x^2+(-8x)+7=6x^2-8x+7$
