Answer:
The top one I'm pretty sure.
First, distribute the y into the parentheses;

Set all equal to 0;

That can't be factored normally, so use the quadratic formula;

The square root of 1034 cannot be simplified, so the solution(s) are:

and
=0.3(4x-8)-0.5(-2.4x+4)
=1.2x-2.4-0.5(-2.4x+4)
=1.2x-2.4+1.2x-2
=2.4x-4.4
