Question

(2x^5 + 3y^4) * (-4x^2 + 9y^4)

Answer 1

are we supposed to solve this???

Answer 2

18x^5y^4+27y^8−8x^7−12x^2y^4

Explanation:

(2x^5+3y^4)(−4x^2+9y^4)

=(2x^5+3y^4)(−4x^2+9y^4)

=(2x^5)(−4x^2)+(2x^5)(9y^4)+(3y^4)(−4x^2)+(3y^4)(9y^4)

=−8x^7+18x^5y^4−12x^2y^4+27y^8

=18x^5y^4+27y^8−8x^7−12x^2y^4
