Which is an example of using the distributive property to multiply -5x^3(3x^2+3x-1) ?

Let y = and z = . translate "z less than y" into an algebraic expression, and solve it.

Simplify the expression 3x(x – 12x) + 3x2 – 2(x – 2)2. which statements are true about the process and simplified product? check all that apply. the term –2(x – 2)2 is simplified by first squaring the expression x – 2. the simplified product is a binomial. after multiplying, the like terms are combined by adding and subtracting. the parentheses are eliminated through multiplication. the final simplified product is –28x2 +8x – 8.
