WebThis tells us that the function must have 1 positive real zero. There is a similar relationship between the number of sign changes in f (− x) f (− x) and the number of negative real zeros. In this case, f (− x) f (− x) has 3 sign changes. This tells us that f (x) f (x) could have 3 or 1 negative real zeros. WebJan 12, 2024 · The zeros of f (x) are the values of x where f (x) = 0. That is where: x5 +x3 − 6x = 0. x(x4 +x2 − 6) = 0. Hence x = 0 or x4 + x2 −6 = 0. Let z = x2. ∴ z2 + z −6 = 0. (z …

Web3 years ago. Take any polynomial first of all, factorize all the polynomial to a form like this, say [2x-x] [10x-8x], and now equate this = 0 to earn zeroes of the polynomial. To know the zero of the polynomial either any one of the brackets should be equal to zero. Now in the first bracket, it turns out to be 2x-x=x so x = 0... hair loss from medication treatment
