Question

1)(-2x^3+xy^2)+(x^2y-1)+(x^2y-xy^2+3x^3)

Answer 1

Ответ:

Объяснение:

1)(-2x³+xy²)+(x²y-1)+(x²y-xy²+3x³)=

=-2x³+xy² + x²y-1 +x²y-xy²+3x³=

=-x³+2x²y-1

Answer 2

To simplify the expression (-2x^3 + xy^2) + (x^2y - 1) + (x^2y - xy^2 + 3x^3), you can combine like terms by adding or subtracting the coefficients of the same variables. Here's how you can do it step by step:

Step 1: Group like terms together: (-2x^3 + 3x^3) + (xy^2 + x^2y - xy^2) - 1

Step 2: Combine the like terms within each group: (x^3) + (x^2y) - 1

So, the simplified expression is: x^3 + x^2y - 1
