Answer 1

$\huge\red{AnsWeR}$

$1)ab (2ab²- 3a²b) + a³b²$

$=>2a²b³-3a³b²+a³b²$

$=>2a²b³-2a³b²$

$2)x(x²+ 1) + y(y²-1)-(x - y)$

$=>x³+x+y³-y-x+y$

$=>x³+y³$

$3)x²y(x³-2x)+2xy(x²-x⁴)$

$=>x^5y-2x³y+2x³y-2x^5y$

$=>x^5y-2x^5y-2x³y+2x³y$

$=>-x^5y$

Answer 2

Answer:

(1) (2ab²+3a²b-4ab) - (3ab-8ab²+2a²b) = ab( 10b + a - 7)

Step-by-step explanation:  

(1) 2ab²+3a²b-4ab ; 3ab-8ab²+2a²b Subtract the second polynomial from the first.

2ab²+3a²b-4ab

3ab-8ab²+2a²b

(2ab²+3a²b-4ab) - (3ab-8ab²+2a²b)

= 2ab²+3a²b-4ab -3ab + 8ab² - 2a²b

= 2ab² + 8ab²  + 3a²b - - 2a²b - 4ab - 3ab

= 10ab² + a²b - 7ab

= ab( 10b + a - 7)
