6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1
2(3x + 4) + 5x - 2
5x + 4 = 3x - 2Subtract 4 from both sides:5x = 3x - 6Subtract 2x from both sides:2x = 6Divide both sides by 2:x = -3
3x-4=5x+6 gives: 2x=-10 which gives x=-5
f(x) = 3x2 + 5x + 2fprime(x) = 6x + 5
2x + 3x = 5x.
2x + 3x = 5x
No. 3x plus 2x = 5x. 3x multiplied by 2x = 6x²
5x+8x+3x-2x = 14x
2x+3x = 5x
5x+(6-3x)+8=5x+6-3x+8=2x+14 2x + 14
5x3 - 3x2 + 2x = x*(5x2 - 3x + 2) The quadratic has no real factors.
6x2 + 5x - 6 is factored out to (2x + 3)(3x - 2).
3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3
5x + 4 - 3x + 5 + 2x - 9 = 4x
5x
3x2 + 5x + 2 is a quadratic expression that can be factored as follows: 3x2 + 5x + 2 = 3x2 + 3x + 2x + 2 = 3x(x + 1) + 2(x + 1) = (3x + 2)(x + 1)
