Question

The question is in the photo. Need C and D.

Answer 1

Given:

C)

`2x^2+30y-3y^2+4xy-14-x`

Simplify the above expression,

`2x^2+30y-3y^2+4xy-14-x=2x^2-3y^2-x+30y+4xy-14`

As there is no like terms in this expression,

Answer:

`2x^2-3y^2-x+30y+4xy-14`

D)

`20+3xy-3xy+y^2+10-y^2`

Simplify the expression,

`\begin{gathered} 20+3xy-3xy+y^2+10-y^2 \\ =20+10+(3xy-3xy)+(y^2-y^2) \\ =30+0+0 \\ =30 \end{gathered}`

Answer: 30
