Best ResponseYou've already chosen the best response.1This isn't exactly an equation since there's no equals sign. Is the equation supposed to be \[3x(4x + x^3)\]? You need to multiply what's inside the parenthesis by the 3x on the outside.

Best ResponseYou've already chosen the best response.0okay so it like 4x3 = 12 right or is it 4x4x4= 64 then 3x3x3= 27 so the answer is 64,27

Best ResponseYou've already chosen the best response.1The former was about right, actually. Since the 3x is on the outside, you multiply both the 4x and the x^3 by it. Take a look at them separately. 4x * 3x = 4 * x * 3 * x You can only multiply like terms. 4 and 3 are both numbers, and x is a variable that you don't know the value of. 4 * 3 * x * x = 12 * x * x So this part comes out to \[12x^2 \] Can you figure out what the full equation will look like?

Best ResponseYou've already chosen the best response.1Wait, is it \[3*(4x + x^3)\] or \[3x*(4x+x^3)\]?
