3x%5E2-5x-2=0...use quadratic formula

x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+ ........a=3, b=-5, and c=-2

x+=+%28-%28-5%29+%2B-+sqrt%28+%28-5%29%5E2-4%2A3%2A%28-2%29+%29%29%2F%282%2A3%29+

x+=+%285+%2B-+sqrt%28+25%2B24+%29%29%2F6+

x+=+%285+%2B-+sqrt%28+49+%29%29%2F6+

x+=+%285+%2B-+7%29%2F6+

solutions are:

x+=+%285+%2B+7%29%2F6+

x+=+12%2F6+

x+=+2+

or

x+=+%285+-+7%29%2F6+

x+=+-2%2F6+

x+=+-1%2F3+
