zero
It can't be factored because the discriminant is less than zero.
72-4*4*4 = -15 The discriminant is less than zero so there's no solutions to the quadratic equation.
It's a quadratic expression which can't be factorized because its discriminant is less than zero.
The discriminant of the equation ... (b2-4ac) = (225-160) ... is real and positive, so the roots are real and unequal.
The discriminant is 0.
The discriminant is 33.
5, if the numbers after the "x" are supposed to be powers
zero
Discriminant = b2-4ac = (-2)2-(4*4*4) = -60
Fifth degree - the highest power of x that appears.
It can't be factored because the discriminant is less than zero.
72-4*4*4 = -15 The discriminant is less than zero so there's no solutions to the quadratic equation.
The coefficients are a = 4, b = -3, c = -8. The discriminant is calculated with the formula b2 - 4ac, so just replace the coefficients in this formula.
The given quadratic expression can not be factorized because its discriminant is less than zero.
It's a quadratic expression which can't be factorized because its discriminant is less than zero.
Use the discriminant to determine the nature of the roots of 4x2 + 15x + 10 = 0.
