Can the standard deviation or variance be negative?
No, a standard deviation or variance does not have a negative sign. The reason for this is that the deviations from the mean are squared in the formula. Deviations are squared to get rid of signs. In Absolute mean deviation, sum of the deviations is taken ignoring the signs, but there is no justification for doing so. (deviations are not squared here)
What is the standard form of 12 squared?
The standard form of 12 squared is 122
What is the discriminate of 3x squared minus 5x plus 4 equals 0?
The discriminant b2-4ac is -23
What is 2x squared plus x squared?
Oh, dude, that's like basic math, right? So, 2x squared plus x squared is just 3x squared. It's like adding apples to apples, but with math. Easy peasy lemon squeezy!
What is the answer to negative 3 squared?
Nine. A negative times a negative is a positive.
What is the discriminant of x squared equals 4?
The discriminant is 16
X squared minus 3x plus 5?
This quadratic expression cannot be factored because its discriminant is less than zero.
3x squared minus 3x plus 2?
This quadratic expression cannot be factored because its discriminant is less than zero
What is the value of the discriminant of the polynomial 4x squared 7x 4?
If you mean: 4x squared+7x+4 then the discriminant is -15

The discriminant, for what it is worth in an example such as this, is 11.
What is the discriminant of 4x squared plus 5x equals 6?
The discriminant is 121.
How do you factor 9x squared plus 3x plus 2?
It can't be factored because the discriminant of this quadratic expression is less than zero.
Discriminant for 4x squared plus 4x plus 1?
B squared -4ac is the discriminant. you get 0, which means it will have one rational solution.
Would you factor x squared minus x plus 9 by factoring?
The discriminant of this quadratic expression is less than zero therefore it cannot be factored.
Which expression is equivelant to 7 negative 2 squared?
(7)-2 = (1/7)2
