Question

Simplify the following expression:

Answer 1

Answer:

$3x^2 -12x+y$

Step-by-step 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.
