Question

Find the square of following using the identities: i)(2a + 5b )2 ii)(6x -7)(6x +7)​

Answer 1

Answer:

Step-by-step explanation:

(6x−7)(6x+7)

using identity(a+b)(a−b)=a2−b2

(6x−7)(6x+7)=(6x)2−(7)2

(6x−7)(6x+7)=36x2−49

Answer 2

Answer:

x/((2x-1)(2x+1)(4x^2+1))=A/(2x-1)+B/(2x+1)+(Cx+D)/(4x^2+1)`. To determine the values of A, B,... `int x/(16x^4-1)dx`. To solve using distributive proverty
