Question

simlify using suitable identity (0.4m-0.5n)​

Answer 1

Step-by-step explanation:

(0.4p−0.5q)2

Using,(a−b)2=a2−2ab+b2

=(0.4p)2−2(0.4p)(0.5q)+(0.5q)2

=0.16p2−0.4pq+0.25q2

Answer 2

Answer:

(0.4m-0.5n)

Step-by-step explanation:

use here (a-b)²=a²-b²+2ab

(0.4m)² - (0.5n)² +2(0.4m)(0.5n)

0.16m² -0.25n² +0.40mn
