The derivative of 2x2 + 4x + 8 is 4x+4.

If: 4x+(-12) = 8 then 4x = 20 and x = 5

4x+8

5x + 3 - 4 + 4x = 9x -1

If the equation is y = 4x + 8, then the standard form is 4x - y + 8 = 0

8 + y = 4x8 + y - 4x = 4x - 4x 8 + y - 4x = 0 8 - 4x + y = 0

3x-8

collect like terms and you get 4x + 5x + 8 - 3 ie 9x +5

4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3

16x

25

Simplify 4x + 3 = 2x + 8 2x = 5 x =2½

-6x-6 -or- -6(x+1)

This would simplify as 4x-5

-4x + 8 = -4 -4x + 8 - 8 = -4 -8 -4x = -12 -4x/-4 = -12/-4 x = 3

x=5

(4x ^2 + 3) + (3x ^2 + 8) = ( 4x^2 + 3x^2 ) + (3+8) = 7x^2 + 11

4x+8

7x+8

4x+32=-4x+16x4x+32=12x-4x -4x32=8x/8 /84=x

(2x - 8)(-4x + 4) = -8x2 + 40x - 32

2x - 5 - 4x + 8= 2x - 4x - 5 + 8= -2x + 3

4x2+4x-8 4(x2+x-2) and (4x+8)(x-1)

3x + x + 8 = 204x + 8 = 204x = 12x = 3

4x + 8
