Question

Using Identifies find
(6m - 5n)2
​

Answer 1

Step-by-step explanation:

using identity

(a-b)²=a²+b²-2ab

(6m-5n)²=(6m)²+(5n)²-2.6m.5n

(6m-5n)²=36m²+25n²-60mn

Answer 2

Answer:

36m²- 60mn + 25n²

Step-by-step explanation:

(6m - 5n)² is in the form (a-b)²

we know that,

(a-b)² = a² - 2ab + b²

Therefore,

=(6m)² - 2(6m×5n) + (5n)²

=36m² - 60mn + 25n².
