y=2x^2-37/2x-15

Explanation:

Let's use FOIL to simplify this problem and get rid of the parentheses:

y=(4x+3)(x/2-5)
y=(4x)(x/2)+(4x)(-5)+(3)(x/2)+(3)(-5)
y=(4x^2)/2+(-20x)+3/2x+(-15)
y=2x^2-20x+3/2x-15
y=2x^2-37/2x-15

Since we are in standard form (terms are in descending order based on their degrees), this is our answer.
