Question

2do + a
6. What should be added to 3y2 - 4x – 3x2 – 5 to obtain x - 2y + 6?​

Answer 1

Given : -3x² + 3y² - 4x -5 (= p, let)

To obtain : x² - 2y + 6 (= q, let)

We just need to subtract q from p

therefore p - q

= -3x² + 3y² - 4x -5 - (x² - 2y + 6)

= -3x² + 3y² - 4x -5 - x² + 2y - 6

= (-3x² - x²) + 3y² - 4x + 2y + (-5 - 6)

= - 4x² + 3y² - 4x + 2y - 11

this is what you actually need to add....

I hope it may help you....!!!

Thanks
