WebThere is a root at x=2, because: (2−2) (22+2×2+4) = (0)(22+2×2+4) And we can then solve the quadratic x2+2x+4 and we are done. 3. Graphically. Graph the polynomial and see where it crosses the x-axis. We can enter the polynomial into the Function Grapher, and then zoom in to find where it crosses the x-axis. WebJul 16, 2024 · So a multiple root of a ( x) can be found by checking whether a ( x) and a ′ ( x) have a common root, i.e. by finding the roots of the greatest common divisor of a ( x) and a ′ ( x). In your case a ( x) = 4 x 4 + 5 x 2 + 7 x + 2, and it follows that. gcd ( a ( x), a ′ ( x)) = 2 x + 1. Therefore x = − 1 / 2 is a multiple root of a ( x ...

WebFrom the quadratic formula, x = -b/2a +/- (sqrt (bb-4ac))/2a If 1 root is non-real, then the discriminant is negative, and both roots have an imaginary component; in one root it's added to -b/2a, in the other subtracted. So there must be 2 non-real roots. If 1 root is real, then the discriminant is either + or 0.
