x4+6x3-2x-12
(x3-2)(x+6)
(-2)^4 = -2 x -2 x-2 x-2 = +16 ( a minus times a minus is plus)
2 to the 4th power times 5 to the 3rd power = 2,000
4(64 - 125b) or -4(125b - 64)
That factors to 5(x - 4)(x + 4)(x2 + 16)
2 to the 4th power = 16 multiplied by 5 = 80 plus 5 to the 2nd power = 25 mulitiplied by 7 = 255
A 7th degree polynomial.
(-2)^4 = -2 x -2 x-2 x-2 = +16 ( a minus times a minus is plus)
3x3x3x3 + 3x3x3 = 81 + 27 = 108
x = plus or minus two thirds
Infinity.
