- $7/50$

Start by simplifying the parentheses first
= ${(3-1)/5}^2$ - $3/10$

= $(2/5)^2$ - $3/10$

= $4/25$ - $3/10$ . Now make the denominators same equal to the lowest common denominator of 25 and 10. This would be 50

= $8/50$ - $15/50$

= - $7/50$

How do you simplify (3/5 - 1/5)^2 + (3/2)(-1/5)(3/5 - 1/5)^2 + (3/2)(-1/5)?
