Question

Simplify. -x^2 - 3xy + 6y + 2x^2 - 8 + 5xy - x^2 + 14 A x^2 + 8xy + 6y + 6 B 8xy + 6y + 6 C -x^2 + 2xy + 6y + 22 D 2xy + 6y + 6

Answer 1

The given expression is

`-x^2-3xy+6y+2x^2-8+5xy-x^2+14`

We have to combine like terms, let's organize the terms first

`-x^2+2x^2-x^2-3xy+5xy+6y-8+14`

Now, we reduce them

`\begin{gathered} -2x^2+2x^2-3xy+5xy+6y-8+14 \\ 0x^2+2xy+6y+6 \\ 2xy+6y+6 \end{gathered}`

Hence, the right answer is D.
