Use the x-intercept method to find all real solutions of the equation.
x^3-8x^2+9x+18=0

a.

Step-by-step explanation:

The given equation is;

To solve by the x-intercept method we need to graph the corresponding function using a graphing calculator or software.

The corresponding function is

The solution to is where the graph touches the x-axis.

We can see from the graph  that; the x-intercepts are;

(-1,0),(3,0) and (6,0).

Therefore the real solutions are:

I’m sorry i can’t u

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
