Question

sub: (7m^3n-8m^2n^2)

from(8m^2n+2m^2n^2)​

Answer 1

Step-by-step explanation:

8m³n + 2m²n² - (7m³n - 8m²n²)

8m³n + 2m²n² - 7m³n + 8m²n²

m³n + 9m²n²

m²n (m - 9n)

Answer 2

Step-by-step explanation:

$(8m {}^{2} n + 2m {}^{2} n {}^{2} ) - (7m {}^{3} n - 8m {}^{2} n {}^{2})$

$8m {}^{2} n - 7m {}^{3} n + 2m {}^{2} n {}^{2} + 8m {}^{2} n {}^{2}$

$8m {}^{2} n - 7m {}^{3} n + 10m {}^{2} n {}^{2}$
