Starting with
5x%5E2+%2B+2x+=+3
Set the equation equal to 0
5x%5E2+%2B+2x+-+3+=+0
...
Thinking of multiples of 3 and mutliples of 5 that will subtract to 2.
(x - )(x + ) mixed signs due to + 2 and -3
...
(5x-3)(x+1)=0
Check with FOIL
5x%5E2+%2B+5x+-+3x+-+3
...
(5x-3)(x+1)=0
5x-3=0, so x = 3%2F5
x+1=0, so x = -1
