Answer 4

try open parentheses:8x"2+5-3x"2+x-7
then:5x"2+x-2

Answer 5

idk

Answer 6

\[(8x ^{2} + 5) - (3x ^{2} -x + 7)\]
\[5x ^{2} + x - 12\]

Argh, I'm stuck right now.. Someone continue my work?

Answer 7

To simplify the expression (8x2 + 5) − (3x2 − x + 7):
First, we look at the first term of the first polynomial and find if there are like terms with the other polynomial. In this case, we have 8x2 and 3x2, when subtracted would give us 5x2.
