You can put this solution on YOUR website!
+144=+10x+%2B+x%5E2+...........rearrange the terms
+144=++x%5E2%2B10x+
++x%5E2%2B10x-144=0+............use quadratic formula

x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+

x+=+%28-10+%2B-+sqrt%28+10%5E2-4%2A1%2A%28-144%29+%29%29%2F%282%2A1%29+
x+=+%28-10+%2B-+sqrt%28100%2B576+%29%29%2F2+
x+=+%28-10+%2B-+sqrt%28+676+%29%29%2F2+
x+=+%28-10+%2B-+26+%29%2F2+
solutions:

x+=+%28-10+%2B+26+%29%2F2+
x+=+16%2F2+
highlight%28x+=+8%29+
and
x+=+%28-10-+26+%29%2F2+
x+=+-36%2F2+
highlight%28x+=+-18%29+
