Answer:
(5x + [tex]\frac{3}{10}[/tex] )(3x - [tex]\frac{7}{10}[/tex])
Step-by-step explanation:
The expression is a difference of squares and factors in general as
a² - b² = (a + b)(a - b)
Then
(4x - [tex]\frac{1}{5}[/tex] )² - (x + [tex]\frac{1}{2}[/tex] )²
= (4x - [tex]\frac{1}{5}[/tex] + x + [tex]\frac{1}{2}[/tex] )(4x -
= (5x + [tex]\frac{3}{10}[/tex] )(3x - [tex]\frac{7}{10}[/tex] )
