x%5E2%2B6x-5=0

x+=+%28-6+%2B-+sqrt%28+6%5E2-4%2A1%2A%28-5%29+%29%29%2F%282%2A1%29+

x+=+%28-6+%2B-+sqrt%28+36%2B20+%29%29%2F2+

x+=+%28-6+%2B-+sqrt%28+56+%29%29%2F2+
x+=+%28-6+%2B-+sqrt%284%2A14+%29%29%2F2+
x+=+%28-6+%2B-+2sqrt%2814+%29%29%2F2+
x+=+%28-6+%2B-+2%2A3.74%29%2F2+
x+=+%28-6+%2B-+7.48%29%2F2+
solutions:
x+=+%28-6+%2B+7.48%29%2F2+
x+=+1.48%2F2+
x+=+0.74+
or
x+=+%28-6+-7.48%29%2F2+
x+=+-13.48%2F2+
x+=-6.74+
