Question

subtract 5x²-4y²+6y-3 from 7x²-4xy+8y²+5x-3y​

Answer 1

Answer: 2x²+12y²-4xy+5x-9y+3

Explanation: Let A = 5x2-4y2+6y-3

B = 7x2-4xy+8y2+5x-3y

According to the problem given,

B-A = 7x²-4xy+8y²+5x-3y -

(5x²-4y²+6y-3 )

= 7x²-4xy+8y²+5x-3y -5x²+4y²-6y+3

= (7-5)x²+(8+4)y²-4xy+5x-(3+6)y+3

= 2x²+12y²-4xy+5x-9y+3
