-3r^2 + 26r - 2 = 0
x+=+%28-26+%2B-+sqrt%28+26%5E2-4%2A-3%2A-2+%29%29%2F%282%2A-3%29+
.
x+=+%28-26+%2B-+sqrt%28+676-24+%29%29%2F%28-6%29+
.
x+=+%28-26+%2B-+sqrt%28+652+%29%29%2F%28-6%29+
.
x+=+%28-26+%2B-+2sqrt%28163+%29%29%2F%28-6%29+
.
x+=+-2%2813+%2B-+1sqrt%28163+%29%29%2F%28-6%29+
.
x+=+%2813+%2B-+1sqrt%28163+%29%29%2F%283%29+
.
x = 8.589 and x= .07761
