Question

find the product using sutable identity (2x+5)(2x-5) ​

Answer 1

Answer:

= (a+b)(a-b)

= a^2 - b^2

= (2x)^2 - 5^2

= 4x^2 - 25

Answer 2

Answer:

hey mate here is your answer .

Step-by-step explanation:

(2x+5) (2x-5)

=> 2x(2x-5) + 5(2x-5)

=> 4x-10x + 10x - 25

=> 4x -25.

here (a-b)^2 identity is used.

a^2+2ab-b^2.
