See a solution process below:

First, remove all of the terms from parenthesis. Be careful to handle the signs of each individual term correctly:

#50x - 3 + 8x^3 + 7x^2 + x + 4#

Next, group like terms:

#8x^3 + 7x^2 + 50x + x - 3 + 4#

Now, combine like terms:

#8x^3 + 7x^2 + 50x + 1x - 3 + 4#

#8x^3 + 7x^2 + (50 + 1)x + (-3 + 4)#

#8x^3 + 7x^2 + 51x + 1#
