#20v^2 - v - 12#

To simplify this expression we need to cross multiply the terms in the parenthesis on the left by each term in the parenthesis on the right:

#(4v*5v) - (4v*4) + (3*5v) - (3*4)#

#20v^2 - 16v + 15v - 12#

Now, we can combine like terms to complete the simplification:

#20v^2 + (-16 + 15)v - 12#

#20v^2 - 1v - 12#

#20v^2 - v - 12#
