Use the x-intercept method to find all real solutions of the equation. x^3-8x^2+17x-10=0
Question
Answer:
f(2) = 8 - 32 + 34 - 10 = 0so one real solution is x = 2 and x - 2 is a factor.,
Dividing the function by x -2 gives
x^2 - 6x + 5
x^2 - 6x + 5 = 0
(x - 5)(x - 1) = 0
x = 1 , 5
All real roots are 1,2 and 5.
