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

Answer:

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

Step-by-step 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 $3x^2-10x-y$.
