Question

(2x²y²+3y²z²) and (9z²x²-7x²y²)
please solve​

Answer 1

Answer:

3x¹²y⁸z⁴

Step-by-step explanation:

First multiply

2x²y²(9z²x²-7x²y²)

and

3y²z²(9z²x²-7x²y²)

18x⁴y²-14x⁴y²+27y²z⁴x²-21x²y²z²

separate positive and negative

18x⁴y²+27y²x²=44x⁶y⁴z²

-14x⁴y²21x²y²z²=35x⁶y⁴z²

44x⁶y⁴z³-35x⁶y⁴z²

=3x¹²y⁸z⁴
