y=2x%5E2-%283x-5%29
y=2x%5E2-3x%2B5....to solve, set y=0
0+=2x%5E2-3x%2B5.........apply quadratic formula
x%5B1%2C2%5D=%28-b+%2B-+sqrt+%28b%5E2+-4%2Aa%2Ac+%29%29+%2F+%282%2Aa%29
x%5B1%2C2%5D=%28-%28-3%29+%2B-+sqrt+%28%28-3%29%5E2+-4%2A2%2A5+%29%29+%2F+%282%2A2%29
x%5B1%2C2%5D=%283+%2B-+sqrt+%289+-+40+%29%29+%2F+4
x%5B1%2C2%5D=%283+%2B-+sqrt+%28-+31+%29%29+%2F+4
x%5B1%2C2%5D=%283+%2B-+sqrt+%28%28-1%29+31+%29%29+%2F+4
x%5B1%2C2%5D=%283+%2B-+5.57i%29%2F+4
x%5B1%5D=%283+%2B+5.57i%29%2F+4
x%5B2%5D=%283+-+5.57i%29%2F+4
