x=0 or 4 or 6

Explanation:

x^3-10x^2+24x=0

Factor,

x(x^2-10x+24)=0

Factor,

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

x=0,x=4,x=6

Explanation:

"take out a "color(blue)"common factor " x

x(x^2-10x+24)=0

"the factors of + 24 which sum to - 10 are - 4 and - 6"

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

"equate each factor to zero and solve for x"

rArrx=0

rArrx-4=0rArrx=4

x-6=0rArrx=6
