10x2-5x-5 = (10x+5)(x-1)
As written, -5x + 9x = 4x 4x - 4 = 4(x - 1) If that's -5x2 + 9x - 4, that factors to -(x - 1)(5x - 4)
......x^2-5x+2 ------------------------ x-1)x^3-6x^2+7x-2 ......x^3-x^2 -------------------------- ..............-5x^2+7x ..............-5x^2+5x ------------------------- ..........................2x-2 ..........................2x-2 -------------------------- .............................0 The quotient is x^2-5x+2
5x2 + x - 6 = (5x + 6)(x - 1) 5x2 - x - 6 = (5x - 6)(x + 1)
2x squared - 5x - 3 = (2x +1)(x -3)

5x-1+2= 5x+1
5x - 1 = 24 5x - 1 + 1 = 24 + 1 5x = 25 5x/5 = 25/5 x = 5

5x+1=20 5x=20-1 5x=19 5x/5=19/5 x=19/5
4 + 5x = 1 5x = 1 - 4 5x = -3 x = -3/5 x = -0.6
y = 5x + 1 y - 1 = 5x (y - 1) / 5 = x
y = 5x + 1 is nota direct variation.y = 5x + 1 is nota direct variation.y = 5x + 1 is nota direct variation.y = 5x + 1 is nota direct variation.
Derivative with respect to 'x' of (5x)1/2 = (1/2) (5x)-1/2 (5) = 2.5/sqrt(5x)
x=1 2/3 How?: 2x-4+3 = 5x-6 2x-1 = 5x-6 2x-1+1 = 5x-6+1 2x = 5x-5 2x-5x = 5x-5x-5 -3x = -5 -3x/-3 = -5/-3 x = 5/3 x = 1 2/3
5x-4x = 1
