Question

Victoria was given the expression -3x + xᶺ2 – 8 + 4x – 3xᶺ2 – 2 and asked to simplify it. How can she simplify the expression?

Answer 1

Answer:
`-2x^2+x-10`

Explanation:

The expression
`-3x+x^2-8+4x-3x^2-2` is a polynomial of degree 2, because the highest exponent of the variable "x" is 2.

Then, to simplify the expression, Victoria needs to:

Order the expression:

`x^2-3x^2+4x-3x-8-2`

Add the like terms:

`-2x^2+x-8`

Then, the simplified expression is finally:
`-2x^2+x-10`

Answer 2

-2x^2 +x -10

Explanation:

-3x + xᶺ2 – 8 + 4x – 3xᶺ2 – 2

Combine like terms

x^2 - 3x^2 -3x+4x -8-2

-2x^2 +x -10
