Question

Use the x-intercept method to find all real solutions of the equation.

Answer 1

x^3 - 8x + 17x - 10

Answer 2

Hold on though the answered are completly different.. ll post them

Answer 3

the factors of -10 might beoine root
eg +2 or -2
try f(-2):-
= -8 -32- 34 + 10 = not = 0

try f(2);- 8 - 32 +34 - 10 = 0

so 2 is one solution

Answer 4

now if we divide the function by (x-2) we can get a quadratic equation which can be solved to get other 2 roots

Answer 5

use long division

Answer 6

so its a
