+x%5E2+%2B+298x+%2B+600+
Set it equal to zero, then
subtract +600+ from both sides
+x%5E2+%2B+298x+=+-600+
Complete the square
Take 1/2 of +298+, square it,
then add it to both sides
+x%5E2+%2B+298x+%2B+%28298%2F2%29%5E2+=+-600+%2B+%28298%2F2%29%5E2+
+x%5E2+%2B+298x+%2B+22201+=+-600+%2B+22201+
+x%5E2+%2B+298x+%2B+22201+=+21601+
+%28+x+%2B+149+%29%5E2+=+146.9728%5E2+
+x+%2B+149+=+146.9728+
+x+=+-149+%2B+146.9728+
+x+=+-2.0272+
and
+x+%2B+149+=+-146.9728+
+x+=+-295.9728+
------------------
+%28+x+%2B+2.0272+%29%2A%28+x+%2B+295.9728+%29+
+x%5E2+%2B+2.0272x+%2B+295.9728x+%2B+2.0272%2A295.9728+
+x%5E2+%2B+298x+%2B+599.996+
