Question

1. Add 2x2–5x2y2+2xy and 6xy+4x2-7 and subtract the result from –xy+x2+7x2y2

Answer 1

Answer:

Step-by-step explanation:

Adding the first two polynomials given,

(2x² -5x²y² + 2xy) + (6xy + 4x² -7)

2x² - 5x²y² + 2xy + 6xy + 4x² - 7

6x² - 5x²y² + 8xy - 7

Now we need to subtract the sum from the polynomial given,

(-xy +x² + 7x²y²) - (6x² - 5x²y² + 8xy - 7)

-xy + x² + 7x²y² - 6x² + 5x²y² - 8xy + 7

12x²y² - 9xy - 5x² + 7

hope this helps ☺️
