Question

What should be subtracted from x² to get 3x² - 2y?

Answer 1

Answer:

Let z be the quantity being subtracted.

∴−32x2+23xy+2y2−z=3x2−2xy−27y

∴−32x2+23xy+2y2−z=3x2−2xy−27y∴z=−(3x2−2xy−27y)−32x2+23xy+2y2

∴−32x2+23xy+2y2−z=3x2−2xy−27y∴z=−(3x2−2xy−27y)−32x2+23xy+2y2∴z=−311x2+27xy+2y2+27y

Hence, the quantity to be subtracted is −311x2+27xy+2y2+27y.
