7 + ( 9 x ( 3 - 1 ) ) = 25
= 53 9x3 + 9x2 + 5x1+ 3x1 27 + 18 + 5 + 3
yes
This is non-linear
(3x + 5)(3x^2 + 4)
7 + ( 9 x ( 3 - 1 ) ) = 25
= 53 9x3 + 9x2 + 5x1+ 3x1 27 + 18 + 5 + 3
9x3=27.
yes
If that's -9x^3 - 3x^2 + 3x + 1, that factors to (1 - 3x^2)(1 + 3x)
This is non-linear
(3x + 5)(3x^2 + 4)
10
(3x2 + 2x + 1)
9*3=27 8*22=176 27 + 7 + 176=210
(x + 2)(3x - 1)(3x + 1)
