x%5E2+-2x-2%2B98
=x%5E2+-2x%2B96
=x%5E2+-2x%2B96.......use quadratic formula to solve for x

x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+ .....a=1, b=-2, c=96

x+=+%28-%28-2%29+%2B-+sqrt%28+%28-2%29%5E2-4%2A1%2A96+%29%29%2F%282%2A1%29+


x+=+%282+%2B-+sqrt%284-384+%29%29%2F2+

x+=+%282+%2B-+sqrt%28-380+%29%29%2F2+

x+=+%282+%2B-+sqrt%28-1%2A4%2895%29+%29%29%2F2+

x+=+%282+%2B-+2i%2Asqrt%2895%29%29%2F2+

x1+=+%282+%2B2i%2Asqrt%2895%29%29%2F2+.........simplify

x1+=+1+%2Bi%2Asqrt%2895%29

x2+=+%282+-2i%2Asqrt%2895%29%29%2F2+.........simplify
x1+=+1+-i%2Asqrt%2895%29
