Use the x-intercept method to find all real solutions of the equation. x^3-8x^2+17x-10=0
abruzzese [7]

Answer:

 x^3-8x^2+17x-10=(x-5)(x-2)(x-1)  

Step-by-step explanation:

Given : Equation - x^3-8x^2+17x-10=0

To Find : All real solutions of the equation

Step1 - Write the equation :

x^3-8x^2+17x-10=0

Step 2 :  To find the x-intercept we plot the graph,

when we plot the graph the points where y=0 are the x-intercept

Step 3: Points where y=0 are 5,2,1 (shown in the attached graph)

Therefore, (x-5)(x-2)(x-1) are the solutions of the equation.

Hence,  x^3-8x^2+17x-10=(x-5)(x-2)(x-1)
