If a equal 4 x cube 3x - 19 b is equals to x cube 8 x square - 7x ...
To find the value of a - b - c, we first need to determine the values of a, b, and c.

Given:
a = 4x^3
b = 3x - 19
c = -5x^3 - 6x + 20

Now let's substitute the given values into the expression a - b - c.

a - b - c = (4x^3) - (3x - 19) - (-5x^3 - 6x + 20)

Simplifying the expression by removing parentheses and combining like terms:

= 4x^3 - 3x + 19 + 5x^3 + 6x - 20

Combining like terms:

= (4x^3 + 5x^3) + (-3x + 6x) + (19 - 20)

= 9x^3 + 3x - 1

Therefore, a - b - c = 9x^3 + 3x - 1.

So, the value of a - b - c is 9x^3 + 3x - 1.
