This quadratic equation has no real roots because its discriminant is less than zero.
The roots are: x = -5 and x = -9
It has roots x = 2.618 and x = 0.38197
There are no real root. The complex roots are: [-5 +/- sqrt(-3)] / 2
To find which has imaginary roots, use the discriminant of the quadratic formula (b2 - 4ac) and see if it's less than 0. (The quadratic formula corresponds to general form of a quadratic equation, y = ax2 + bx + c)A) x2 - 1 = 0= 0 - 4(1)(-1) = 4Therefore, the roots are not imaginary.B) x2 - 2 = 0= 0 - 4(1)(-2) = 8Therefore, the roots are not imaginary.C) x2 + x + 1 = 0= 1 - 4(1)(1) = -3Therefore, the roots are imaginary.D) x2 - x - 1 = 0= 1 - 4(1)(-1) = 5Therefore, the roots are not imaginary.The equation x2 + x + 1 = 0 has imaginary roots.
I'm not familiar with the "bisection method" to find the roots of 2x2-5x+1 = 0 but by completing the square or using the quadratic equation formula you'll find that the solution is: x = (5 + or - the square root of 17) over 4 Hope that helps.

Type your answer here. Find the radius for a circle with the equation x2 plus y2 equals 9? ..
You can find the roots with the quadratic equation (a = 1, b = 3, c = -5).
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.
x = 2 and x = 4
The discriminant is -27 and so 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.
The equation to find the volume of a rectangular object is (a) volume equals length times width times height.
x^2 + 14x + 40 factorises as (x + 10)(x + 4) so the roots are x = -10, -4.
