Example: Factorize, a^{2}+4a+4. Solution: Given that, a^{2}+4a+4. We can write this as, a^{2}+2.a.2+2^{2}. This is in the form of (a+b)^{2 }= a^{2}+2ab+b^{2}. Here a = a and b = 2, substitute these values in the formula, we get, (a+2)^{2}. Directions: Solve the following problems. Also write at least 10 examples of your own.
