Question

(5x-2)^2-(2x-1)^2

Answer 1

(5x-2)²-(2x-1)²=(5x-2-2x+1)(5x-2+2x-1)=(3x-1)(7x-3)

Answer 2

   (5x - 2)² - (2x - 1)²

= (5x - 2 + 2x - 1) (5x - 2 - 2x + 1)

= (7x - 3) (3x - 1)

 

 

Answer 3

\(\left(5x-2\right)^2-\left(2x-1\right)^2\)

\(=\left(5x-2-2x+1\right)\left(5x-2+2x-1\right)\)

\(=\left(3x-1\right)\left(7x-3\right)\)
