Simplify (x+2)^3
Problem
Solution
Identify the expression as a binomial raised to the third power, which follows the pattern
(a+b)3 Apply the formula for the cube of a binomial:
(a+b)3=a3+3*a2*b+3*a*b2+b3 Substitute
a=x andb=2 into the expansion formula.Expand the terms:
x3+3*(x2)*(2)+3*(x)*(2)+2 Simplify each term by performing the multiplication and exponentiation.
Calculate the final coefficients:
x3+6*x2+12*x+8
