Question

Simplify the following expression:

2x − 6y + 3x2 + 7y − 14x.

3x2 + 12x + y
3x2 − 12x − y
3x2 − 12x + y
3x2 − 12x − 13y

Answer 1

3x2 - 12x + y

Explanation:

Answer 2

`3x^2 -12x+y`

Explanation:

Given expression,

`2x - 6y + 3x^2 + 7y - 14x`

`=(2-14)x + (-6 + 7)y + 3x^2`

`=-12x + y + 3x^2`

`\implies 2x - 6y + 3x2 + 7y - 14x=3x^2 -12x+y`

Since, further simplification is not possible,

Hence, THIRD option is correct.
