Question

subtract the sum of 3x²+2xy-2y² and 5y²-7xy from 5x² from 5x²-2y²-3xy

Answer 1

Answer:

2x²-5y²+2xy

Step-by-step explanation:

sum = 3x²+2xy-2y²+5y²-7xy

=3x²+3y²-5xy

subtraction :-

= 5x²-2y²-3xy-(3x²+3y²-5xy)

= 5x²-2y²-3xy -3x² -3y²+5xy

= 2x²-5y²+2xy

thank you

Answer 2

Answer:

(-7x²-2xy+5y²

Step-by-step explanation:

{(3x²+2xy-2y²)+(5y²-7xy)}-(5x²)-(5x²-2y²-3xy)=

(3x²-5xy+3y²)-(5x²)-(5x²-2y²-3xy)=

(-7x²-2xy+5y²)
