What is factorization?
Factorization is the transformation of an expression expressed in the form of a sum into the form of a product.
The following is the basic formula for factorization.
\begin{align} &x^2+\left(a+b\right)x+ab=\left(x+a\right)\left(x+b\right)\\[+5pt] &x^2\pm 2xy+y^2=\left(x\pm y\right)^2\\[+5pt] &x^2-y^2=\left(x+y\right)\left(x-y\right) \end{align}
Example
Example 1
Factorize \(\displaystyle x^2+4x+4 \).
Solution
\[ x^2+4x+4=\left(x+2\right)^2 \]
Example 2
Factorize \(\displaystyle 25x^2-16y^2 \).
Solution
\[ 25x^2-16y^2=\left(5x+4y\right)\left(5x-4y\right) \]
