Simplify (x-4)^3
Problem
Solution
Identify the expression as a binomial cube of the form
(a−b)3 Apply the formula for the cube of a binomial, which is
(a−b)3=a3−3*a2*b+3*a*b2−b3 Substitute
a=x andb=4 into the formula.Expand the terms:
x3−3*(x2)*(4)+3*(x)*(4)−4 Simplify each term by performing the multiplication and exponentiation.
Calculate the final coefficients:
x3−12*x2+3*(x)*(16)−64 Combine all parts to reach the final polynomial form.
