-4x^2 (3x^2 + 25x - 7)
disa [49]
In the instructions for this problem I am told to distribute -4x^2. Why?
the order of operations is the order in which to simlify
if you look inside the parenthases, all like terms have been combined so the inside of parenthasees have already been simlified
expanding the exponents won't make it any easier so we move to distriubiting (or mulitplying)
so then the next step is mulitply -4x^2 by the trinomial


<span>In the order of operations you must do problems inside parentheses first. Why does multiplying monomials by polynomials change this? </span>multiplying monomails by polynomials does not change this

<span>Would the answer come out different if I did the work according to the order of operations?
no because distributing first is what you should do if you follow order of operations
