You can calculate a value if you assign a value to variable "x".
x2 - 9x + 20 = (x - 4)( x - 5)
(x + 2)(3x - 1)(3x + 1)
9x + 1x = 10x.
x+5+3x-7+9x+3-4x Collect like terms: 9x+1
If you mean: x squared+9x+14 = 0 then by using the quadratic equation formula x = -2 or x = -7
(9x + 7)(x - 2)
(x+1)(x+8)
(9x2 + 7)(9x2 - 7) = 81x4 - 49
x2 - 9x + 8 = (x-1)(x-8)
x2-9x can be factored by taking x out of each term x(x-9)
It is a quadratic equation in x.
(9x)2 +9x/(45x)2 +81= 9+9x/86
(x + 12)(x - 3)
It is: (x-2)(x-7) when factored
It is (x-1)(x-8) when factored
Integral : 9x + 8 = 9(x squared)/2 + 8x Differential : 9x +8 = 9
