You cannot factor negative radical numbers because the square of a number must always be positive. A negative number multiplied by a negative number produces a positive number. So, it is impossible to have a negative radical.
The radical symbol ( âˆš ) followed by a line above what's in the radical, designates positive square root.
It is the RADICAL SIGN , its definition is - the symbol used to indicate a nonnegitive square root.
Technically,no. A radical equation has a radical (Square root) in it, and has two solutions because the square root can be positive or negative.
The square of a positive number is positive. By the way, the square of a negative number is also positive.
When you square a real number the answer is positive,
The square root (radical) of 5 is about 2.2361 (an irrational number)
using basic math principles, you can't find the square root of a negative number because in order for a number to be a square root, you have to multiply it by itself to get your radical. since a negative times a negative and a positive times a positive are both positive, it is impossible to find the square root of a negative number
If the number inside the radical is a perfect square or a ratio of perfect squares.
you have to square the outside number and then multiply it by the number inside the squareroot sign.
