Question

Explain, in your own words, the step-by-step process to simplifying the expression below. Include the simplified answer in your explanation.

(10x^2 - 5) - (3x^2 - 2x + 7)

anonymous · Answer

so, first distribute the -1
10x^2 - 5 - 3x^2 + 2x - 7

now simplify by adding like terms
7x^2 + 2x - 12

anonymous · Answer

You have to distribute the negative to (3x^2 - 2x + 7), which then would become (-3x^2 + 2x - 7). Now I would add or subtract like terms:
10x^2 - 5 - 3x^2 + 2x - 7
7x^2 + 2x - 5.
