(9x + 7)(x - 2)

(x+1)(x+8)

If you mean: x squared+9x+14 = 0 then by using the quadratic equation formula x = -2 or x = -7

(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(x^2 + 2x + 9)

(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

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

x = Â±2

9x squared plus 16 = 0 factored is plus and minus 4/3 i.

9x2 + 8x - 1 = (9x - 1)(x + 1)

(2x+3)(x+3)

- 8x2

2x2+9x+9 = (2x+3)(x+3) when factored

9x squared plus 16 = 0 factored is plus and minus 4/3 i.

If you mean: x2+9x+20 then it is (x+4)(x+5) = 0 when factored

2x2-9x+4 = (2x-1)(x-4) when factored

x squared plus 9x plus 20.

You can calculate a value if you assign a value to variable "x".
