Presumably you mean: -2x2-3x+41
If so then the discriminant is: (-3)2-4*-2*41 = 337
The expession is: i/2+i
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)
The discriminant b2-4ac is -23
The standard form of 12 squared is 122
x2+2x is a Mathematical expression. Its factors are x and x+2.
Nine. A negative times a negative is a positive.
the expression "b2-4ac" with respect to quadratic equations is called the discriminant. the discriminant of the equation tells whether or not the roots will be real numbers or not. If the discriminant is negative, then the roots are imaginary.
The discriminant is 16
This quadratic expression cannot be factored because its discriminant is less than zero.
This quadratic expression cannot be factored because its discriminant is less than zero
It can't be factored because its discriminant is less than zero
It can't be factored because the discriminant of this quadratic expression is less than zero.
If you mean: 4x squared+7x+4 then the discriminant is -15
The discriminant is 121.
The discriminant, for what it is worth in an example such as this, is 11.
B squared -4ac is the discriminant. you get 0, which means it will have one rational solution.
The discriminant of this quadratic expression is less than zero therefore it cannot be factored.
(7)-2 = (1/7)2
