No real roots
If the discriminant of a quadratic equation is zero then it has equal roots. If the discriminant is greater than zero then there are two different roots. If the discriminant is less than zero then there are no real roots.
This quadratic equation has no real roots because its discriminant is less than zero.
If the discriminant of a quadratic equation is zero then it has two identical roots.
No real roots but the roots are a pair of complex conjugates.
The discriminant of x2+3x+4 is -7 therfore it has no real roots.
The discriminant is -27 and so there are no real roots.
Use the discriminant to determine the nature of the roots of 4x2 + 15x + 10 = 0.
General form of a quadratic equation is: ax2+b+c = 0 The discriminant is: b2-4ac If the discriminant equals zero then there are two equal roots If the discriminant is greater than zero then there are two different roots If the discriminant is less than zero then there are no real roots
The discriminant of the equation ... (b2-4ac) = (225-160) ... is real and positive, so the roots are real and unequal.
Child stop trying to cheat on your homework!
With a negative discriminant, the two solutions are imaginary.
It has no real roots.
No.
If you mean b^2 -4ac then it is the discriminant of a quadratic equation. If the discriminant equals 0 then the equation has 2 equal roots. If the discriminant is greater than 0 then the equation has 2 different roots. If the discriminant is less than 0 then it has no real roots.
yes
If the discriminant of a quadratic equation is zero then it has equal roots. If the discriminant is greater than zero then there are two different roots. If the discriminant is less than zero then there are no real roots.
If the discriminant is negative, the roots will be two unreal complex conjugates. If the discriminate is positive the roots will be real.
