Question

8. What should be added to (x²y -2x + 3) to get (-7x²y – 1)?​

Answer 1

Step-by-step explanation:

x²y-2x+3 +(-8x²y+2x-4)

=> x²y-2x+3-8x²y+2x-4

= x²y-8x²y-2x+2x+3-4

= -7x²y-1

Answer 2

Answer:

What should be added to (x²y -2x + 3) to get (-7x²y – 1)?

STEP BY STEP EXPLANATION :-

Let X denote the required algebraic expression.

Then, (x²y - 2x +3) + X = -7x²y - 1

Hence, the required expression X

= -7x²y - 1 - (x²y - 2x + 3)

= -7x²y - 1 - x²y + 2x -3

= -7x²y - x²y + 2x - 1 -3

= -8x²y + 2x - 4

✅ HENCE THE REQUIRED ALGEBRAIC EXPRESSION IS

-8X²Y + 2X -4
