Finding the Value of an Expression

Write polynom...

Question

Write polynomial $P$ as a product of linear factors: $P (x) = x^{2} - 4$

Open in App

Solution

Given the polynomial $P (x) = x^{2} - 4$
We need to factor $P (x)$ as follows:
$P (x) = x^{2} - 4 = (x + 2) (x - 2)$
Hence, $P (x) = (x + 2) (x - 2)$
