Question

add2×3-5×^2y^2+2×y and 6×y +4×^2 -7 and subtract the result from -×y+×^2+7×^2y^2​

Answer 1

Answer:

-9xy-3x²+2x²y²-1

Step-by-step explanation:

According to the question,

(-xy+x²+7x²y²) - (2×3-5x²y²+2xy+6xy+4x²-7)

=> -xy+x²+7x²y² - (5x²y²+8xy+4x²-1)

=> -xy+x²+7x²y²-5x²y²-8xy-4x²-1)

=> -xy-8xy+x²-4x²+7x²y²-5x²y²-1

=> -9xy-3x²+2x²y²-1
