6x plus 3 equals 8x plus 14 when solved mathematically is equal to x = -5.5.

2x + 15 = 8x + 43 -6x = 28 x = -6 / 28 = -3 / 14

-6x-17 ≥ 8x+25Add 17 to both sides:-6x ≥ 8x+42Subtract 8x from both sides:-14x ≥ 42Divide both sides by -14. Since we are diving by a negative number, flip the sign.x ≤ -3

8x-3+6x-1 = 12x+614x-4 = 12x+614x-12x = 6+42x = 10x = 5

Multiplying out the brackets it then is: 6x+8x+8-3 = 14x+5 when simplified

-14x -14 + 6x= 2.7 1) Combine the like terms; -14x + 6x. Which leaves you with: -8x -14=2.7 2) Add the -14 to the 2.7 -8x=16.7 3) The divide; x/8 and 16.7/8 Which leaves you with: x= 2.0875

6x+1-x-3 = 8x-5-8 5x-2 = 8x-13 5x-8x = -13+2 -3x = -11 x = 11/3

(4x - 3)(2x + 3)

8x3 + 4x2 + 6x + 3 = 4x2(2x + 1) + 3(2x + 1) = (2x + 1)(4x2 + 3)

8x^3 - 12x^2 + 6x - 9 = (8x^3 - 12x^2) + (6x - 9) = 4x^2(2x - 3) + 3(2x - 3) = (4x^2 + 3)(2x - 3)

74

8x2 + 6x - 9 = 8x2 + 12x - 6x - 9 = 4x(2x + 3) - 3(2x + 3) = (2x + 3)(4x - 3)
