26x%5E2-15x=0...use quadratic formula

x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+.......a=26, b=-15, and c=0

x+=+%28-%28-15%29+%2B-+sqrt%28+%28-15%29%5E2-4%2A26%2A0+%29%29%2F%282%2A26%29+

x+=+%2815+%2B-+sqrt%28+225%29%29%2F52+

x+=+%2815+%2B-+15%29%2F52+

solutions:

x+=+%2815+%2B+15%29%2F52+
x+=+30%2F52+
x+=+15%2F26+
x+=+0.58+
or
x+=+%2815+-15%29%2F52+
x+=+0%2F52+
x+=+0
