What is 3x plus 1 times 2x plus 4?
(3x+1)(2x+4) = 6x2+4+2x+12x = 6x2+14x+4
What is the fractorization of 3x3 plus 6x2 - 24x?
3x3 + 6x2 - 24x = 3x(x2 + 2x - 8) = 3x(x2 + 4x - 2x - 8) = 3x[ x(x + 4) - 2(x + 4) ] = 3x(x - 2)(x + 4)
What does x equal 5x plus 4 equals 3x-2?
5x + 4 = 3x - 2Subtract 4 from both sides:5x = 3x - 6Subtract 2x from both sides:2x = 6Divide both sides by 2:x = -3
What is 3x plus 2 x-1 plus 2x-4 x plus 2 equals 5?
Your notation is hard to read. Did you mean 3x+2x-1+2x-4x+2=5? You have a lot of weird spaces that make your x's look like multiplication or something. The first step is to get variables on one side of the equation and numbers on the other. Add 1 and subtract 2 from 5, giving 3x+2x+2x-4x=4 Now, simply do the math on the variables. 3x+2x+2x-4x giving you 7x-4x which equals 3x, so that means 3x=4(from our earlier work) divide both sides by 3, 3x/3=4/3 gives us x=4/3 or x=1 1/3 or x=1.3333333 however you like.
3x plus 2 x - 8 - 12?
3x + 2x - 8 = 125x - 8 = 125x = 20x = 4
