Explanation:

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

Factor,

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

Factor,

#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#
