x3 - 4x factor the common factor out
= x(x2 - 4) factor the difference of the squares
= x(x + 2)(x - 2)
If you want to find the values of x which make the given expression equal to zero, then it will happen if
x = 0, or
x + 2 = 0, which yields x = -2, or
x - 2 = 2; x = 2

Solve x2 plus 4x plus 3 equals 0?
x2 + 4x + 3 = 0 (x + 1)(x + 3) = 0 x ∈ {-3, -1}
Solve the equation 4x-7y equals 12 for y in terms of x then solve it for x in terms of y?
4x - 7y = 12-7y = -4x + 12y = (4/7)x - (12/7)======================4x - 7y = 124x = 7y + 12x = (7/4)x + 3
4x-3x-3 x equals 3?
4x to the 3rd power -4x to the 2nd power -43 when x=3
Solve 3 4x equals 19?
Is there an operator missing from this question? * 3 + 4x = 19 => x = 4 * 3 - 4x = 19 => x = -4 * 3 . 4x = 19 => x = 19/12
Darius is asked to solve the equqtion x plus 5 equals 4x over 3?
x + 5 = 4x/3 Solve for x multiply both sides of the equation by 3... 3 * (x + 5) = 3 * (4x/3) 3x + 15 = 4x subtract 3x from both sides of the equation (3x + 15) - 3x = (4x) - 3x 15 = x x = 15

What is the solution set of 4x - 3 9?
If the question gives 4x-3=9, then we can solve: 4x-3=9 4x=6 x=3/2, or 1.5
Solve for x 5 plus 4x equals 3?
x= -.5
Solve x2 plus 4x plus 3 equals 0?
x2 + 4x + 3 = 0 (x + 1)(x + 3) = 0 x ∈ {-3, -1}
What is 4x plus 3 - x equals 4x - 32?
To solve 4x+3-x=4x-32 we use the additive property of equaility and add -3 to both sidesSo 4x-x=4x-32-3Simplify this by now subtracting 4x from both sides.-x=-35 or x=35Check it.3-35=-32 so it works.
Solve the equation 4x-7y equals 12 for y in terms of x then solve it for x in terms of y?
4x - 7y = 12-7y = -4x + 12y = (4/7)x - (12/7)======================4x - 7y = 124x = 7y + 12x = (7/4)x + 3
