Question

How do you do this??????

Answer 1

`((1)/(2) - (3)/(4))^(2) + (5)/(10)` # Make the denominators in the grouped expression the same

`((2)/(4) - (3)/(4))^(2) + (5)/(10)` # Subtract

`((-1)/(4))^(2) + (5)/(10)` # Square

`(1)/(16) + (5)/(10)` # Make the denominators the same

`(10)/(160) + (80)/(160)` # Add

`(90)/(160)` # Simplify

`(9)/(16)`

Hope this helps!
