Find a polynomial, which if substituted for M will make the equation an identity: M + (5x2 –2xy) = 6x2 +9xy–y2

Gennadij [26K]

Answer: you just solve for M

M = x^2 + 11xy – y^2

Step-by-step explanation:

M + (5x^2 –2xy) = 6x^2 +9xy–y^2

M = 6x^2–5x^2 + 9xy+2xy – y^2

M = x^2 + 11xy – y^2

Check:

x^2 + 11xy – y^2 + 5x^2 – 2xy

6x^2 + 9xy – y^2
