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).
What else can I help you with?
If the value of a discriminant is 0 what does that tell us about the type and number of roots?
The original equation, ax2 + bx + c = 0 has two equal roots whose value is -b/2a.
How does discriminant enable us to identify the number and type of solutions roots of a quadratic function?
If the quadratic equation is ax2 + bx + c = 0 then if the discriminant, b2 - 4ac is greater than 0: there are two real roots = [-b + or - sqrt(b2 - 4ac)]/2a equal to 0: there are two real coincidental roots, with the value -b/2a less than 0: there are two complex roots = [-b + or - i*sqrt(b2 - 4ac)]/2a where i is the imaginary square root of -1. The answer to the third case (discr<0) may be given as "there are no real roots".
What is the value of the discriminant for the quadratic equation d2-7d plus 8 equals 0?
b2 - 4ac72 - 4(1)(8)49 - 32= 17---------this tells us, by being positive, that there are two real roots in this quadratic .
What is the equation b squared minus 4ac known as?
Oh, dude, that's like the quadratic formula, you know? It's the one where you gotta plug in those numbers and hope for the best. So, yeah, b squared minus 4ac is just a fancy way of saying "let's find those roots, man."
Why are there slender roots and stout roots?
because of the gravity of the earth sampak to the moon that creates seed that when the seed is planted it creates roots and they call it slenderbecause it uses slenda that can make our body fit that can make our crush attract to us

What is the discriminant?
If a quadratic equation is ax2+bx+cthen we can learn something about the roots withoutcompletely solving the quadratic formula.The discriminant is b2-4ac. You may recognize this as part of the quadratic formula.If the value is a non-zero perfect square, there are 2 rational rootsIf the value is an imperfect square, there are 2 irrational rootsIf the value is zero, there is 1 rational root (parabola vertex is on the x-axis)If the value is negative, there are imaginary roots (no intersection with x-axis)The discriminant, therefore, tells us the nature of the roots.

How has science effected human?
only by thought and vanity to make us believe we are better than our roots, the nature, mother earth
What does the standard deviation tell us?
standard deviation is the square roots of variance, a measure of spread or variability of data . it is given by (variance)^1/2
