Answer 1

Answer:

see first one I don't know

but second one you have to subtract the first one from the second one

put the like terms under each other

like 3x^2 under 3x^2 so it becomes easy for cancellation

similarly -2x under -5x

so the order will be 3x^2-3x^2 -2x+5x+5xy+9xy-7-8 and remaining will be the answer

it's just cancellation

please mark as brainliest

but before that do the sum

put the like terms together
