The numbers are: -4 +square root of 12 and -4 -square root of 12
When you multiply a negative number by a positive number then the product is always negative. When you multiply a positive number by a negative number then the product is always negative. ( - 2 ) ( + 3 ) = - 6 ( - 4 ) ( 1 ) = - 4 ( - 1 ) 2 = - 2 ( + 2 ) ( - 2 ) = - 4 ( 3 ) ( - 2 ) = - 6 4 ( - 2 ) = - 8
4. i is just the imaginarY number used in an equatiOn, where there is a negative root (not possible to have a negative root) All yoU do is multiply the negative Root with a negative one, and you'll See your answer. absoluTe valUe turns any negative number into a Positive, even an Imaginary number. Do this and you'll be fine with your trigonometry!
Every number has two square roots ... a positive one and a negative one. Example: +2 and -2 are both square roots of 4, because when you multiply either of them by itself, the answer is 4. The positive square root of a number is the square root that's not negative. The non-negative square root of a number is the positive one.
The negative root is not defined because if you multiply two negative numbers together, the product is still positive. 2*2 =4 (-2)*(-2) =4 So, there is no real answer to the square root of a negative number. In higher math however, the square root of negative one is actually defined as i. The set of i is a set of imaginary numbers, and they have some special properties.
-4 + -5 + -2 + -1 = -12 (negative 12).
-3 + -7 + 5 + -4 + -6 = -15
No because the answers are 6 and 4 respectively.
None, it involves the square root of a negative number so the roots are imaginary.
- 4 + (- 4) = - 8
It depends on whether you take the positive square root of 4 (YES) or the negative square root of 4 (No).
The total sum is -12 or negative twelve.
8 + -4 + -8 = -4
0, of course! 4+-4=4-4. One negative plus one positive equals one negative.
It is not possible for a negative number to have a square root. Any square root is the number that, when you multiply it by ITSELF it will equal the number you are square rooting. Example: The square root of 4 is 2. 2 times itself(2x2) is 4. Negative numbers are imposable to square root because the square root cannot be multiplied by its opposite ( i.e. -2 times 2 or 4 times -4), it must be multiplied by itself. Any positive multiplied by a positive is a positive, and any negative multiplied by a negative is a positive. So any number times ITSELF will always be a positive. ( i.e. -4 time -4 is 16 as 4 times 4 is also sixteen.) If a squared square root is always positive then a negative number cannot have a square root. It's imposable.* * * * *True for basic mathematics but not so for more advanced mathematics. There is a whole area of mathematics called complex mathematics which is based on the square root of negative numbers. The square root of -1 is defined as i.
The square root of -1 is the imaginary number i.So the square root of -4 = 2i
The square root of 4 is 2, if you multiply that by the square root of 49, which is 7, you get 14.
-4+0-(-4)+(-4)-1= -4+0+4-4-1= -5
4 of anything plus 4 more of it totals up to 8 of the same thing.
