- Divide the numerator and denominator by the greatest common factor.
- Write down the reduced fraction.
How do you simplify algebraic?
To simplify any algebraic expression, the following are the basic rules and steps:
- Remove any grouping symbol such as brackets and parentheses by multiplying factors.
- Use the exponent rule to remove grouping if the terms are containing exponents.
- Combine the like terms by addition or subtraction.
- Combine the constants.
Why is negative 2 squared negative?
“This is because to square a number just means to multiply it by itself. For example, (−2) squared is (−2)(−2)=4. Note that this is positive because when you multiply two negative numbers you get a positive result.” – This, of course, is the exact opposite of what was asked, but it’s the given response.
Why is i the square root of negative one?
Here, the term “imaginary” is used because there is no real number having a negative square. There are two complex square roots of −1, namely i and −i, just as there are two complex square roots of every real number other than zero (which has one double square root).
When a square root is negative?
The square root of a negative number does not exist among the set of Real Numbers. really meant. In an effort to address this problem, mathematicians “created” a new number, i, which was referred to as an “imaginary number”, since it was not in the set of “Real Numbers”. This new number was viewed with much skepticism.
Is 0 a real number?
What Are Real Numbers? Edit. Real numbers consist of zero (0), the positive and negative integers (-3, -1, 2, 4), and all the fractional and decimal values in between (0.4, 3.1415927, 1/2). Real numbers are divided into rational and irrational numbers.
Does a square root have two answers?
It has multiple answers so why do we pick the positive one? if x2=16⟹x=√16 or x=−√16 for respectively the positive and negative solution. This implies that the square root function has a single answer and we must negate its answer to obtain the second solution.
What does 2 sq mean?
In math, the squared symbol (2) is an arithmetic operator that signifies multiplying a number by itself. The “square” of a number is the product of the number and itself. Multiplying a number by itself is called “squaring” the number. Squaring a number is the same as raising that number to the power of two.
Why does 49 have two possible square roots?
There is no equation to solve, thus there are no solutions to speak of. Square root of positive real numbers are defined to take the positive root. It is from definition but not from calculation. x2=49 does have 2 roots, but we will only take the positive one for square root.

Is 25 a square number?
A square number is the result when a number has been multiplied by itself. For example, 25 is a square number because it’s 5 lots of 5, or 5 x 5.
