54 + -90x
27x2 - 90x + 27 = 9*(3x - 1)*(x - 3)
120 - 90x = 210
First, if you have two equations like, for instance .90x+2000 and .40x+3500 then you would set them equal to each other like this ( .90x+2000=.40x+3500). Then you would solve for x by simplifying the equations as far down as you can.
Half of half of half of one half is one sixteenth (0.0625).
54 + -90x
As long as the equation is 9x3 + 27x2 - 90x = 0, the answer is : 27 + 27x2 - 90x = 0 9x3 = 27 27 + 54 - 90x = 0 27x2 = 54 81 - 90x = 0 27 + 54 = 81 81 = 90x add 90x to each side 9/10 = x divide each side by 90 x = .9
90x=1977x=1977/90x=21.966666667

27x2 - 90x + 27 = 9*(3x - 1)*(x - 3)
90x
90x
9(10x + 9y)
y/90
If you mean: 27x2-90x+27 then divide all terms by 9 which is then 3x2-10x+3 And when factored it is: (3x-1)(x-3)
If you mean: 2x-90x+10 then it can be simplified to 10-88x by collecting like terms together.
