Factor 64-x^2
Problem
Solution
Identify the expression as a difference of two squares, which follows the general form
a2−b2 Determine the values of
a andb by taking the square root of each term.Calculate
a=√(,64)=8 andb=√(,x2)=x Apply the formula for the difference of squares, which is
a2−b2=(a−b)*(a+b) Substitute the values of
a andb into the formula to get(8−x)*(8+x)
