You multiply 3 by x, and 3 by -2. Then you add everything together.
3x-2 and 2x-9, now for this it kind of depends on how the equation is set out if it set out likw this 3x-2+2x-9 then you would answer it like this: -6x+-18x= 12x
3(x plus 2) expanded --> 3x+6 Check out wolframalpha.com for more explanation (not advertising)
Oh, isn't that just lovely? To expand x(3x + 2), you simply distribute the x to both terms inside the parentheses. So, you would have 3x^2 + 2x. Just like painting happy little trees, math can be a beautiful and calming experience when you take it step by step.
To find the equivalent trinomial, we need to expand the expression ((3x - 2)(x + 4)). Using the distributive property (FOIL method), we have: [ 3x \cdot x + 3x \cdot 4 - 2 \cdot x - 2 \cdot 4 = 3x^2 + 12x - 2x - 8. ] Combining like terms, the equivalent trinomial is (3x^2 + 10x - 8).
3x + 2 = 3x + 6 This is not possible.

x^2 + 3x + 2/(-3x) - x^2 - 2=3x-2+2/(-3x)=3x-2-2/(3x)
3(x plus 3) expanded --> 3x+9
If 2 divided by 3x it is equal to 2/3x
9x2 + 12x + 4 = 9x2 + 6x + 6x + 4 = 3x(3x + 2) + 2(3x + 2) = (3x + 2)(3x + 2) = (3x + 2)2
If you mean: 9x2+3x-2 = (3x+2)(3x-1) when factored
3x * (x - 4) = 3x*x - 3x*4 = 3x^2 - 12x.
3x * (x - 4) = 3x*x - 3x*4 = 3x^2 - 12x.
