Question

efectúa la operación algebraica ( 2x- y)(y+2x)

​

Answer 1

Respuesta:

Take the integral:

integral(2 x - y) (2 x + y) dx

Expanding the integrand (2 x - y) (2 x + y) gives 4 x^2 - y^2:

= integral(4 x^2 - y^2) dx

Integrate the sum term by term and factor out constants:

= 4 integral x^2 dx - y^2 integral1 dx

The integral of x^2 is x^3/3:

= (4 x^3)/3 - y^2 integral1 dx

The integral of 1 is x:

Answer: |

| = (4 x^3)/3 - x y^2 + constant
