4-terms - NOT factored by grouping.
Factor out greatest common factor. 2-terms together. Get down to 3 terms first.
Ok, first of all, just consider the first term:
Is there any GCF to factor out here? Yes, we have t. Therefore:
Ok, let's go back to the problem:
consider the last second two terms:
GCF(-24x-24y)=-24 so -24x-24y=-24(x+y) then ...
A polynomial is factored.
