Question

Find the product of the following : (xy+1)×(5x³y-x²y²+xy³-4) ​

Answer 1

Answer:

5x^4y^2−x^3y^3+x^2y^4+5x^3y−x^2y^2+xy^3−4xy−4

Step-by-step explanation:

because you start with your equation of

(xy+1)(5x^3y−x^2y^2+xy^3−4) which then equals

(xy+1)(5x^3y+−x^2y^2+xy^3+−4) which then gives you the equation of (xy)(5x^3y)+(xy)(−x^2y^2)+(xy)(xy^3)+(xy)(−4)+(1)(5x^3y)+(1)(−x^2y^2)+(1)(xy^3)+(1)(−4) which you would then simplify into the equation of

5x^4y^2−x^3y^3+x^2y^4−4xy+5x^3y−x^2y^2+xy^3−4 which after this equation you are finally left with your answer of

5x^4y^2−x^3y^3+x^2y^4+5x^3y−x^2y^2+xy^3−4xy−4
