Question

What must be subtracted from x2y –3x + 4 toget –7x2y –5x + 1?
pls answer quick I will mark as brainliest

Answer 1

Answer:

Assume "A" is subtracted from 3x4y-2xy4+7x-2y to get 7xy4-5x4y-3x+3y​

ATQ

3x4y-2xy4+7x-2y - A = 7xy4-5x4y-3x+3y​

A = 3x4y-2xy4+7x-2y - 7xy4 + 5x4y + 3x - 3y​

A = 8x4y - 9xy4+ 10x - 5y

Hence 8x4y - 9xy4+ 10x - 5y must be subtracted from 3x4y-2xy4+7x-2y to get 7xy4-5x4y-3x+3y​.
