find the real and complex zeros of the following function f(x)=x^3-5x^2+8x-6

By trial and error we can see that one root is x=3 so (x-3) is a factor. Divide the polynomial by this factor and we get x^2-2x+2. Use the quadratic formula to find the remaining zeroes: x=(2+sqrt(4-8))/2=(2+sqrt(-4))/2=(2+2i)/2=1+i. So the three roots are 3, 1+i, 1-i. (I used synthetic division

complex, rational and real roots

The quintic function should have 5 roots.  The changes of sign (through Descartes) tell us the maximum number of positive roots. Since there are two changes of sign there is a maximum of 2 positive roots. To find the number of negative roots we negate the terms with odd powers and check

Rational Zero Theorem?

both of your equations can be factored x^4-7x^2-144 =(x^2-16)(x^2 +9) =(x-4)(x+4)(x^2+9) giving you 4 and -4 as real roots the second one factors into (x^2-25)(x^2+1) =(x-5)(x+5)(x^2+1) giving you 5 and -5 when you have only x^4, x^2 and a constant, you can factor as above just like ax^2 +bx+c

Finding a polynomial of a given degree with given zeros: Complex zeros

If the polynomial has an even degree, meaning that the highest power of the variable (for example: x) is an even number (for example: x^4), then all the zeroes could be complex. If odd, there must be at least one real zero. A complex zero is given by the complex expression: a+ib, where a and b ar

f(x) =5x^4 -10X^3+X^2-2.5X+20

f(x) = 5x^4 - 10x^3 + x^2 - 2.5x + 20 because it is to the 4th power there are up to 4 roots. by Descarte's there are 4 changes from positive to negative.  So there up to 4 real roots and 2 maybe real and 2 complex. So, there may be 0 to 4 real roots. 2 maybe complex. f

minimun of sqrt(x^4-3x^2+4)+sqrt(x^4-3x^2-8x+20)

f = sqrt(x^4-3x^2+4)+sqrt(x^4-3x^2-8x+20) To find the turning points, differentiate f and set that value to zero. df/dx = (1/2)*(4*x^3-6*x)/sqrt(x^4-3*x^2+4)+(1/2)*(4*x^3-6*x-8)/sqrt(x^4-3*x^2-8*x+20) = 0 (4*x^3-6*x)/sqrt(x^4-3*x^2+4) = -(4*x^3-6*x-8)/sqrt(x^4-3*x^2-8*x+20) cross-multipl
