Question

Simplify the following expression:
2x − 8y + 3x2 + 7y − 12x

Answer 1

combine the like terms

3x2-10x-y

2x and -12x go together, and -8y and 7y go together

Answer 2

The simplified form of given expression is
`3x^2-10x-y`.

Explanation:

The given expression is

`2x-8y+3x^2+7y-12x`

We need to find the simplified form of given expressions.

On combining like terms, we get

`(2x-12x)+(-8y+7y)+3x^2`

On simplification, we get

`(-10x)+(-y)+3x^2`

`-10x-y+3x^2`

Arrange the terms according to the degree.

`3x^2-10x-y`

Therefore the simplified form of given expression is
`3x^2-10x-y`.
