answer please fast !!!​

Answer 1

Answer:

1) 18x^4+27x^3-24x^2+36x-9

Step-by-step explanation:

2). 6x^3-x^2y^2-2xy^3 hope it is useful for u

Answer 2

i) (6x² - 5x + 3)(3x² + 7x - 3)

18x⁴+42x³-18x²-15x³-35x²+15x+9x²+21x-9

18x⁴+42x³-15x³-18x²-35x²+9x²+15x+21x-9

18x⁴+27x³-44x²+21x-9

ii) x²(x - 3y²) - xy(y²- 2xy) - x(y³- 5x²)

x³-3x²y² - xy³+2x²y² - xy³+5x³

x³+5x³-3x²y²+2x²y² - xy³- xy³

6x³-x²y²-2xy³
