The given expression
is equal to 144 or 
<em><u>Solution:</u></em>
Given expression is:

We have to evaluate the above given expression
We know that,


Substituting these in above given expression, we get

Also we know that,

Therefore,

Thus the given expression
is equal to 144 or 
x³ + 8x² + 11x - 20 ← the first on list
given the roots of a polynomial, say x = a, x = b and x = c
then the factors are (x - a), (x - b) and (x - c)
the polynomial is the product of the factors
f(x) = (x - a)(x - b)(x - c)
here x = - 5, x = - 4 and x = 1, hence factors are
(x + 5), (x + 4) and (x - 1)
f(x) =(x + 5)(x + 4)(x - 1) ← expanding factors gives
f(x) = (x² + 9x + 20)(x - 1) = x³ + 8x² + 11x - 20
