+5x%2Ay%5E2-9x%2Ay%2B4x+
Factor out x
+x%2A%28+5y%5E2+-+9y+%2B+4+%29+
Use the quadratic formula
y+=+%28-b+%2B-+sqrt%28+b%5E2+-+4%2Aa%2Ac+%29%29+%2F+%282%2Aa%29+
+a+=+5+
+b+=+-9+
+c+=+4+
y+=+%28-%28-9%29+%2B-+sqrt%28+%28-9%29%5E2+-+4%2A5%2A4+%29%29+%2F+%282%2A5%29+
y+=+%28+9+%2B-+sqrt%28+81+-+80+%29%29+%2F+10+
y+=+%28+9+%2B+1%29+%2F+10+
+y+=+1+
+y+-+1+=+0+
and
+y+=+%28+9+-+1+%29%2F10+
+y+=+4%2F5+
+y+-+4%2F5+=+0+
+5y+-+4+=+0+
The factors are:
+x%2A%28+y-1+%29%2A%28+5y+-+4+%29+
