27x2 - 90x + 27 = 9*(3x - 1)*(x - 3)
Step 1: Divide by 9x: 9x (x2 + 3x - 10) = 9x(x + 5)(x - 2)
54 + -90x

A magnification of 90X means that an object appears 90 times larger than its actual size. This level of magnification is commonly used in microscopy, allowing for detailed observation of small structures. For example, if a cell measures 1 micrometer, it would appear 90 micrometers in size under a 90X magnification.
120 - 90x = 210
Step 1: Divide by 9x: 9x (x2 + 3x - 10) = 9x(x + 5)(x - 2)
54 + -90x
90x
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)
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
If you mean: 2x-90x+10 then it can be simplified to 10-88x by collecting like terms together.
90x=1977x=1977/90x=21.966666667
