Yes it is possible.
+ax%5E2+%2B+bx+%2B+c+-+7+=+0
a%28x%5E2+%2B+%28b%2Fa%29x%29+%2B+c+-+7+=+0
a%28x%5E2+%2B+%28b%2Fa%29x+%2B+b%5E2%2F%284a%5E2%29%29+%2B+c+-+7+=+b%5E2%2F%284a%29
a%28x+%2B+b%2F%282a%29%29%5E2++%2B+c+-+7+-+b%5E2%2F%284a%29+=+0
%28x+%2B+b%2F%282a%29%29%5E2++%2B+%284ac+-+28a+-+b%5E2%29%2F%284a%5E2%29+=+0
%28x+%2B+b%2F%282a%29%29%5E2++-+%28b%5E2+-+4ac+%2B+28a+%29%2F%284a%5E2%29+=+0

It's routine from here...
