[tex](x+4)(x^2-6x+3)[/tex]
First, let's use the distributive property.
[tex]x(x^2-6x+3)+4(x^2-6x+3)[/tex].
Open the parenthesis and use the distributive property again.
[tex](x^3-6x^2+3x)+(4x^2-24x+12)[/tex]
Now, open the parenthesis and combine the like terms.
[tex]x^3-2x^2-21x+12[/tex]
That's your answer. Hope this helps! :)
Note: Use "^" for exponents when asking questions to make things clearer for other answerers. For example, you can write [tex]x^2[/tex] as x^2
