How many complex roots does 6x4 plus x3 - 5 equals 0 have?
It has two complex roots.
Which two values of x are roots of the polynomial below 3x2-3x 1?
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals". There is no sign (plus or minus) before the final 1.
What is the square root of 200?
Any number greater than 0 has two square roots, a positive square root and a corresponding negative square root. Rounded to two decimal places, the square roots of 200 are ±14.14.
What is 2x to the power of 2 minus x to the power of 2?
The question is ambiguous and two possible answers are given below: 2x2 - x2 = x2 or (2x)2 - x2 = 4x2 - x2 = 3x2
How do you factor X to the third power plus Y to the third power?
x^3+y^3 Cube root of the first, x plus cube root of the last, y times What it takes to make the first number, x^2 Opposite sign, - Product of the two cube roots, -xy Then what it takes to make the last. (x+y)(X^2-xy+y^2)
How many roots does 3x2 plus 4x plus 3 have?
two complex
How many roots does 3x2 plus 8x plus 3 have?
two negative
How many complex roots does 6x4 plus x3 - 5 equals 0 have?
It has two complex roots.
3x2 plus 5x plus 10 equals 0?
3x + 5x + 10 = 0a = 3, b = 5, c = 10D = b - 4ac = 25 - 120 = -95Since D < 0, we have two conjugate complex roots.√D = √-95 = i√95x = (- b ± √D)/2ax = -5/6 + [(√95)/6]i or x = -5/6 -[(√95)/6]i
How do you simplify fourth roots?
The answer will depend on the form of the fourth root. Positive real numbers will have two fourth roots which are real and two that are complex. Complex numbers will have four complex roots. However, none of these can be "simplified" in the normal sense of the term.
What is the fourth root of 11?
Two of the four roots are 1.8212 and -1.8212 (approx). The other two roots are complex numbers.
When factored what is the solution set 3x squared plus 2x plus 1equals?
3x2 + 2x + 1 this can not be factor and receive whole numbers. you need to use the quadratic equation. your answer will also have a complex number in it.the complex number will be sqrt of -1 which is equal to i 2+sqrt(-8) / 6 and 2-sqrt(-8) / 6 these two are your answers.
What does the discriminant tell you when solving quadratic equations for the roots?
Whether the equation has 2 distinct roots, repeated roots, or complex roots. If the determinant is smaller than 0 then it has complex roots. If the determinant is 0 then it has repeated roots. If the determinant is greater than 0 then it has two distinct roots.
How many times does the graph of 3x2 plus 8x plus 5 cross the x-axis?
Twice. Between negative two and negative one.
How does the discriminant affect the roots of a quadratic equation?
If the discriminant is negative, the roots will be two unreal complex conjugates. If the discriminate is positive the roots will be real.
Does y equals 3x2-5x plus 1 cross the x-axis?
This can be easily answered using the well-known formulae for solving quadratic equations:y = 3x2 - 5x + 1thenx = (5 +- sqrt(25 - 4*3*1))/6since 25-4*3*1 = 25-12 = 13, which is > 0, this parabola has two intersections with the x-axis (as the quadratic equation has two real roots).
What is five n squared plus two n plus six equals zero?
5n2 + 2n + 6 = 0 is a quadratic equation in the variable n.The equation does not have any real roots. The roots are the complex conjugate pair -0.2 ± 1.077i where i is the imaginary square root of -1.
