Example: Find the value of (48)^{2} using formula. Solution: We can write (48)^{2} = (502)^{2} This is the form of (ab)^{2} = a^{2}  2ab + b^{2} = (50)^{2 }+ 2.50.2 + 2^{2} = 2500  200 + 4 = 2504  200 = 2304 Directions: Solve the following problems using the formula. Also write at least ten examples of your own.
