Zero`s of 6x%2A6x-5x%2B7=0
36x%5E2-5x%2B7=0 ..use quadratic formula
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+

x+=+%28-%28-5%29+%2B-+sqrt%28+%28-5%29%5E2-4%2A36%2A7+%29%29%2F%282%2A36%29+

x+=+%285+%2B-+sqrt%28+25-1008+%29%29%2F72+

x+=+%285+%2B-+sqrt%28+-983+%29%29%2F72+

x+=+%285+%2B-+sqrt%28+-1%2A983+%29%29%2F72+

x+=+%285+%2B-+5.6i%29%2F72+

x+=+5%2F72+%2B-+5.6i%2F72+

x+=0.007+%2B-+0.08i+
solutions:
x+=0.007+%2B+0.08i+
and
x+=0.007+-+0.08i+
