Question

subtract x²-2xy+5y² from 4xy-5x²-y²+6​

Answer 1

Answer:

(4xy - 5x^2 - y^2 + 6) mein se (x^2 - 2xy + 5y^2 -4) subtract karna hai, Right.....toh.....

= (4xy - 5x2 - y2 + 6)  -  (x2 - 2xy + 5y2 - 4)

= 4xy + 2xy - 5x2 - x2 - y2 - 5y2 + 6 + 4

=6xy - 6x2 - 6y2 + 10  

=3xy - 3x2 - 3y2 + 5   <= Answer

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

(4xy - 5x^2 - y^2 + 6) mein se (x^2 - 2xy + 5y^2 -4)

= (4xy - 5x2 - y2 + 6)  -  (x2 - 2xy + 5y2 - 4)

= 4xy + 2xy - 5x2 - x2 - y2 - 5y2 + 6 + 4

=6xy - 6x2 - 6y2 + 10

=3xy - 3x2 - 3y2 + 5
