Identify binomial: Identify the binomial to be squared.The given expression is 4d+1^2. This is a binomial squared, which can be expanded using the formula a+b^2 = a^2 + 2ab + b^2.
Identify values: Identify the values of a and b. In the expression (4d+1)2, a is 4d and b is 1.
Apply formula: Apply the square of a binomial formula.Using the values of a and b, we expand (4d+1)2 as follows:(4d+1)2=(4d)2+2(4d)(1)+(1)2
Simplify expression: Simplify the expression.(4d)2+2(4d)(1)+(1)2=16d2+8d+1
