Question

Combine like terms to simplify the expression.

Answer 1

`\text{Hello there!}\\\\\text{Simplify by combining like-terms:}\\\\6x^2+3y^2+4y^2-2x\\\\\text{Add}\,\,3y^2+4y^2\\\\6x^2+7y^2-2x\\\\\text{There are no more like terms, so your answer is the above}\\\\\boxed{\text{Answer:}\,\,6x^2+7y^2-2x}`

Answer 2

Start by changing the -2x to plus a negative 2x.

So we have 6x² + 3y² + 4y² - 2x.

Note that 3y² and 4y² are like terms because

they are exactly alike except for their coefficients.

So 3y² + 4y² simplifies to 7y².

Although 6x² and -2x look similar, they are not like terms.

So our final answer is 6x² + 7y² + -2x.
