Consider the function f(x) = x^3 - 15x^2 + 50x.? what are the real zeros in this function?

We have

.

To find zeros of this function we equate it with 0

.

First we factor out x

where we find that first zero is .

Then we look at the expression in parentheses

using Viéts rule (factorisation)

we can rewrite the equality

.

If either of the terms is zero then the equality is true so we get two more zeros and .

Hope this helps.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
