You aren't explaining what you need to do with this expression, unless it is actually an equation and you mistyped "+" between the parentheses when you meant "=". That is to say you meant:
It also isn't clear whether you meant or

-4x+5+2x^2+x/2-12
2x^2-3.5x-7
Using the quadratic equation we get:
x=(3.5+-sqrt[-3.5^2-4*2*-7])/2*2
x=(3.5+-sqrt[12.25+56])/4
x=(3.5+-sqrt68.25)/4
x=(3.5+-8.26136)/4
x=(3.5+8.26136)/4
x=11.76136/4
x=2.94 ans.
x=(3.5-8.26136)/4
x=-4.76136/4
x=-1.19 ans.
