(2x+7)(2x-7)
here we use identity ( a+b)(a-b)=a^2-b^2
a=2x,b=7
(2x+7)(2x-7)=(2x)^2-(7)^2
=4x^2-49

Given:-
→(2x+7)(2x-7)
To Find:-
→The expanded form of (2x+7)(2x-7)?
AnsWer:-
★On expanding the equation★
→(2x+7)(2x-7)=(2x)²-(7)²
[°•° (a+b)×(a-b)=a²-b²]
→(2x+7)(2x-7)=4x²-49
๛Hence, On expanding (2x+7)(2x-7) we get 4x²-49 as the Answer
