...meaning you want to put the missing square term onto x(x+3/2), which as is, represents a rectangle which you can rearrange into a square missing a square corner.

2x%5E2%2B3x-5
2%28x%5E2%2B%283%2F2%29x%29-5 ------- the term you want to use is %283%2F%282%2A2%29%29%5E2=9%2F16
highlight%282%28x%5E2%2B%283%2F2%29x%2B9%2F16%29-2%2A%289%2F16%29-5%29 ------ADDING and SUBTRACTING the square term
2%28x%2B3%2F4%29%5E2-9%2F8-5
2%28x%2B3%2F4%29%5E2-9%2F8-40%2F8
