Question

find the solution (2x+1) (2x-1) using the formula (x+a) (x+b) = x^2+(a+b)x+ab ​

Answer 1

Answer:

Let 'x' be 2x, 'a' be 1 and 'b' be -1

Then,

(2x+1) (2x-1)=(2x)^2+[1+(-1)]2x + (-1)(1)

                  = 4x^2+0(2x)-1

                  = 4x^2-1

Therefore the solution is 4x^2-1

Answer 2

Answer:

your answer is here

given (2x+1)(2x-2)

=  (2x)^2 +(1+(-2))x+1*(-2)

=4x^2-x-2
