Question

Find the value of (2x-1) (2x+1) (2x+3), when x = 3.

Answer 1

(2x-1) (2x+1) (2x+3)
(2*3-1)(2*3+1)(2*3+3)
(6-1)(6+1)(6+3)
5*7*9
315

Answer 2

Answer:

315.

Step-by-step explanation:

Given:- (2x-1)(2x+1)(2x+3)

To Find:- The value of the above expression when x=3.

Solution:-

= (2x-1)(2x+1)(2x+3)

Putting x = 3 in the above expression.

= (2 × 3 - 1)(2 × 3 + 1)(2 × 3 + 3)

= (6 - 1)(6 + 1)(6 + 3)

= 5 × 7 × 9

= 315

Hence, The value of the expression  (2x-1)(2x+1)(2x+3) when x = 3 is 315.
