How to find the roots of a function in MATLAB?

To find the roots of a function in MATLAB, you can use the "roots" function for polynomials or the "fzero" function for general functions. The "roots" function calculates the roots of a polynomial, while the "fzero" function finds the root of a general function by iteratively narrowing down the root within a specified interval.

How can one find all rational roots of a polynomial equation?

To find all rational roots of a polynomial equation, you can use the Rational Root Theorem. This theorem states that any rational root of a polynomial equation in the form of (anxn an-1xn-1 ... a1x a0 0) must be a factor of the constant term (a0) divided by a factor of the leading coefficient (an). By testing these possible rational roots using synthetic division or polynomial long division, you can determine which ones are actual roots of the equation.


What are the roots of the polynomial x2 plus 3x plus 5?

You can find the roots with the quadratic equation (a = 1, b = 3, c = -5).


Find the roots of the polynomial given 4x2 - 3x - 5?

No integer roots. Quadratic formula gives 1.55 and -0.81 to the nearest hundredth.


Can you find a third degree polynomial equation with rational coefficients that has the given numbers as roots 3i and 7?

Yes, easily. Even though the question did not ask what the polynomial was, only if I could find it, here is how you would find the polynomial: Since the coefficients are rational, the complex (or imaginary) roots must form a conjugate pair. That is to say, the two complex roots are + 3i and -3i. The third root is 7. So the polynomial, in factorised form, is (x - 3i)(x + 3i)(x - 7) = (x2 + 9)(x - 7) = x3 - 7x2 + 9x - 63
