Question

What should be taken away from 3x² - 4y²+ 5xy+20 to obtain -x²- y²+ 6xy+20​

Answer 1

Aus) we P(x) = 3x² - 4y² + 5xy + g(x) = -x² - y² + 6xy Let Q be sustract from then P(₂) - 0. g(x) = +20 +20 P(x) to obtain goal

3x² - 4y² + 5xy + 20 = Q = -x²_y² +6xy + 20 = 3x²_4y² + 5xy + 2/6 + x²y² - 6xy -20 2 xy]

Hence get gen)
