X=-2.
Subtract 1 from each side: x3 = 64; You might know that 4 cubed is 64, but if you don't then take log 64, divide it by 3 and take the antilog of your answer...
3 + 2 + 25*3 - 6 = 3 + 2 + 75 - 6 = 74
x3 - 3x2 + x - 3 = (x2 +1)( x - 3)
x3 - 3x2 + x - 3 = (x - 3)(x2 + 1)
3 - 3x + x2 - x3 = (1 - x)(x2 + 3)
3 plus 1 plus 4 equals 8
x3+x2+x First, factor out the x: x(x2+x+1) Could stop there, but the rest is factor-able using imaginary numbers: x(x+.5(1+i(3).5)(x+.5(1-i(3).5), where i = (-1).5, or sqrt(-1)
x + 3 = 6xx - x + 3 = 6x - x3 = 5x3/5 = 5x/53/5 = x
Yes.
1.66666666666666666667 because 3 plus 1 plus 1 equals 5 and 5 divided by 3 equals 1.6666666666666666666.7.
42
6+1 equals 7. Plus 3 equals 10. Plus 4 equals 14.
