Question

What is all the real solution of the equation

Answer 1

x=1, or 6, or 4 (D)

Explanation:

x³-11x²+34x-24=0 solve by factorizing

(x-1)(x-6)(x-4)=0

x-1=0

x=1

if x-6=0

x=6

x-4=0

x=4

check : x³-11x²+34x-24=0

x=1 : (1)³-11(1)²+34(1)-24=0

1-11+34-24=-35+35=0 (correct)

x=6 : 6³-11(6)²+34(6)-24=0 (correct)

x=4 : 4³-11(4)²+34(4)-24=0 (correct)
