Find roots of polynomial equationsBill Venables
BThis can be done by factorizing the polynomial to (-1)(-2)(-3), so the roots are 1.2and 3which sum to 6.Another approach is to realize that (-)(-)(-)multiplies out to-(++)+(++)-, and as we're looking for++we can simply read it off the coefficient ofand flip it's...
To find the multiple roots of the polynomial equation 8x3+20x2+6x−9=0, we will follow these steps: Step 1: Define the functionLet f(x)=8x3+20x2+6x−9. Step 2: Find the derivativeWe need to find the first derivative f′(x):f′(x)=ddx(8x3+20x2+6x−9)=24x2+40x+6...
