Simplify the expression.
2x^2+8+3x^3+4x-10
a. 5x^2+4x-2
b. 2x^2+x-10
c. 2x^2-x+10
d. 5x^2+7x-11

Answer 1

ummm can you check you question you may have an incorrect power of x

Answer 2

so I'll assume the highest power is 2

I'll rewrite your expression

\[(2x^2 + 3x^2) + 4x + (8 - 10)\]

can you simplify the brackets...?

Answer 3

it may be easier as

\[(2 + 3)x^2 + 4x +(8 - 10)\]

Answer 4

yeah i made a mistake sorry it was 2 instead of 3
\[5x ^{2}+4x-2\]

Answer 5

thats the correct solution... well done
