Question

3 x cube minus x square -10 x

Answer 1

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

x(3x^2-x-10)=0

x=0, 3x^2 -6x+5x-10=0

3x(x-2)+5(x-2)=0

(3x+5) (x-2)=0

x=0,, x=-5/3 ,,,,, x= 2

hope it helps

Answer 2

hi mate your answer is

• factorise the equation
• you will get two factors
• substitute the value of X in the equation
• that is your answer

squared is ^2 so three squared is  

3^2x^3-3x^2+2x-8 divided by x^2+2

That is close but still no parentheses. They are still free today!

(x^3-3x^2+2x-8)/(x^2+2)  

if anything is like for Eg:2^3 means  2 to the power 3
