Question

multiple [3xy2+4x2]x[3x2-xy2]​

Answer 1

Answer:

5x³y²-x²y^4+12x^4

Step-by-step explanation:

[3xy²+4x²]x[3x²-xy²]

=3xy²[3x²-xy²]+4x²[3x²-xy²]

=9x³y²-x²y^4+12x^4-4x³y²

=5x³y²-x²y^4+12x^4

Answer 2

Step-by-step explanation:

(3xy²+4x²)(3x²-xy²)

(9x³y²-3x²y⁴+12x⁴-4x³y²)

(5x³y²-3x²y⁴+12x⁴)
