Learn moreThe square root of a number:

The square root of a given positive real number is defined as the number multiplied by itself, resulting in the given number.

Example:

The square root of \(64\) is \(8\).

That is, \(\sqrt{64} = \sqrt{8 \times 8} = \sqrt{8^2} = 8\)

The square root of a polynomial:

The square root of a polynomial \(p(x)\) is defined as an expression \(q(x)\), when multiplied with itself, results in the given number \(p(x)\).

That is, \(p(x) = q(x) \times q(x)\)

So, \(\sqrt{p(x)} = |q(x)|\) where \(|q(x)|\) is the absolute of \(q(x)\).

The square root of a polynomial can be determined using two methods.

They are:

**1**. Factorization method

**2**. Long division method
