Negative NumbersWe can also square negative numbers.Example: What happens when we square (−5) ? Answer: (−5) × (−5) = 25 (because a negative times a negative gives a positive)That was interesting!When we square a negative number we get a positive result....
(because anegative times a negative gives a positive) That was interesting! When we square anegativenumber we get apositiveresult. Exactly the same as when we square a positive number: Now remember our definition of a square root? A square root of x isa number r whose square is x: ...
How do you find the square root of a negative number like -5? Complex Numbers: Numbers that cannot be represented on a number line are called complex numbers. {eq}\pi{/eq} is not a complex number because even though it is an unending decimal, we can still represent it on a number ...
Square Root of a Negative Real Number (Imaginary Numbers): SMART Board Resource for Algebra 2 (Grades 6-12) (eLesson Plan)
We know how to find the square root of any positive real number. In a similar way, we can find the square root of a negative number. The difference is that the root is not real. If the value in the radicand is negative, the root is said to be an imaginary num...
