Question

simplify by combining -x²+9x²-3x+7x³-8x​

Answer 1

${Hello!}$

$- {x}^{2} + 9 {x}^{2} - 3x + 7 {x}^{3} - 8x$

Let's arrange to make it more easier

${ - x}^{2} + 9 {x}^{2} - 3x - 8x + 7 {x}^{3}$

Simplifying the same terms

$8 {x}^{2} - 11x + 7 {x}^{3}$

Answer 2

Answer:

The simplified term by combining the expression is 7x³+8x²-11x.

Step-by-step explanation:

Consider the provided expression.

-x²+9x²-3x+7x³-8x​

Now combine the like terms as shown:

7x³-x²+9x²-3x-8x​

Now add or subtract the like terms:

7x³+x²(-1+9)-x(3+8)​

7x³+8x²-11x

Hence, the simplified term by combining the expression is 7x³+8x²-11x
