To solve the expression (4(3x + 2) + 4x), first distribute the 4:
[ 4 \times 3x + 4 \times 2 + 4x = 12x + 8 + 4x. ]
Next, combine like terms:
[ 12x + 4x + 8 = 16x + 8. ]
So the simplified answer is (16x + 8).
The answer to the math problem of 18 minus 4x equals negative 2 is x equals 5.
To justify something in math is to prove it. Example: Justify 4x = 8 when x = 2. When x = 2, 4(2) = 8. Done. By doing this I justified that 4x = 8 when x = 2.
x= 1.5 4x -2=4 <<< Original problem +2 +2 <<< reverse operations (problem requires subtraction, so add to solve) 4x=6 <<< New problem 4x/4=6/4 <<<reverse operations (new problem requires multiplication, so divide to solve) x=1.5 <<< answer
x2-4x-12 = (x-6)(x+2) when factored
Watch me as I do it. Perhaps you can pick up some pointers.-34 = 2 + 4xSubtract 2 from each side of the equation:-36 = 4xDivide each side by 4 :-9 = x

If you mean 3x2+4x-2 = 0 then it can be solved by means of the quadratic equation formulla
The expression 4x^2 - x^2 simplifies to 3x^2. This is because when you subtract x^2 from 4x^2, you are left with 3x^2. The coefficients remain the same, but the variable term is simplified by subtracting the like terms.

4x
Oh, dude, you're hitting me with some math now? Okay, okay, no need to panic. So, when you multiply 3x by 4x, you just gotta multiply the numbers (3 and 4) and then add the exponents (x and x). So, the answer is 12x^2. Easy peasy lemon squeezy!
4x - 3 - 5x + 7 = 6 4x - 5x = 3 - 7 + 6 -1x = 2 x = -2
2+2=?

4x times 2 = 8x
