Question

12. Simplify : [(10x³y² – 15x²y²+ 5xy²) + (2x²y – 3x²y²+ 4) – (6x²y – xy²– 15x³y²)]​

Answer 1

Answer:

25x³y² - 18x²y² + 6xy² + 4

Explanation:

[( 10x³y² - 15x²y² + 5xy²) + (2x²y - 3x²y² + 4) - (6x²y - xy² - 15x³y²)

= 10x³y² - 15x²y² + 5xy² + 2x²y - 3x²y² + 4 - 6x²y + xy² + 15x³y²

= 10x³y² + 15x³y² - 15x²y² - 3x²y² + 5xy² + xy² + 4

= 25x³y² - 18x²y² + 6xy² + 4
