What are 3 outcomes for the discriminant?
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.
How do you find the sum of the roots of the equation x2 plus 5x plus 9 equals 0?
This quadratic equation has no real roots because its discriminant is less than zero.
How do you find the discriminant and number of real solutions to a quadratic equation?
The equation ax^2 + bx + c = 0 where a, b and c are real and a is non-zero has discriminant D = b^2 – 4ac. Then,if D > 0 the equation has two real roots which are distinct;if D = 0 the equation has two real roots which are coincident;if D < 0 the equation has two roots which form a complex conjugate pair (advanced mathematics only).
If the discriminant of an equation is 0?
If the discriminant of a quadratic equation is zero then it has two identical roots.
If the discriminant is negative the equation has?
No real roots but the roots are a pair of complex conjugates.
Use the quadratic equation y equals x2 plus 3x plus 9 Calculate the discriminant to determine the number of real roots?
The discriminant is -27 and so there are no real roots.
Using the word discriminant in sentence?
The discriminant of a quadratic equation helps determine the nature of its roots - whether they are real and distinct, real and equal, or imaginary.
What is a discriminant in a quadratic equation?
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
What do you call an organism that hunts and kills its food?
Use the discriminant to determine the nature of the roots of 4x2 + 15x + 10 = 0.
What is the nature of the roots of 4x2 plus 15x plus 10 equals 0?
The discriminant of the equation ... (b2-4ac) = (225-160) ... is real and positive, so the roots are real and unequal.
What is the discriminant of a quartic equation and how can you determine the real and complex roots from the value of the discriminant?
Child stop trying to cheat on your homework!
Without solving the equation determine the nature of the roots of 2x 2 plus 3x plus 9 0?
With a negative discriminant, the two solutions are imaginary.
Use the discriminant to determine how many real number solutions the quadratic equation -4j to the second power plus 3j - 28 equals 0 has?
It has no real roots.
In the quadratic equation ax2 plus bx plus c 0 if b2 - 4ac?
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.
