Question

Using the horizontal method, add x²+yx+5 and y²-3+2xy and subtract the
sum from 2x² + 2y² + 3xy - 2.​

Answer 1

Answer:

Answer is x²+y²- 4

Step-by-step explanation:

First addition

= x²+yx+5 + y²-3+2xy

=x²+3xy+2+y²

Then subtraction

=(2x²+2y²+3xy-2) - (x²+3xy+2+y²)

=2x²+2y²+3xy-2 - x²-3xy-2-y²

=x²+y²- 4
