Q23. What should be taken away from 3x2 – 4y2 + 5xy + 20 to obtain - x² - y2 + 6xy + 20?
a) 4x2 – 3y2 – XY
b) 4x2+3y2-xy
c) 4x2-3y2 + xy
d) None of these​

Answer 1

Answer:

it is option c subtract both you will get the answer

Answer 2

Answer:

none of these

Step-by-step explanation:

the answer is 4x2-3y2-1xy

to get this answer we should subtract x2-y2+6xy+20 from 3x2-4y2+5xy+20

when we subtract we will change x2+y2-6xy+20 into x2-y2-6xy-20 because of additive inverse.

now we should subtract.

hope it helps.
