(9x)2 +9x/(45x)2 +81= 9+9x/86
Let the symbol ^ mean "to the power" Then 9x^2 + 24x + 16 = (3x + 4)(3x +4) = (3x + 4)^2
(9x + 7)(x - 2)
This is (3x +2)2 so if x is an integer/3, this expression is the square of an integer so cannot be prime. Anything else, and it's not even an integer.
2x2+9x+9 = (2x+3)(x+3) when factored
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
(9x)2 +9x/(45x)2 +81= 9+9x/86
Let the symbol ^ mean "to the power" Then 9x^2 + 24x + 16 = (3x + 4)(3x +4) = (3x + 4)^2
(9x2 + 7)(9x2 - 7) = 81x4 - 49
(9x + 7)(x - 2)
x2 + 9x2 = 10x2
This is (3x +2)2 so if x is an integer/3, this expression is the square of an integer so cannot be prime. Anything else, and it's not even an integer.
81x2 + 72x + 16 = 81x2 + 36x + 36x + 16 = 9x(9x + 4) + 4(9x + 4) = (9x + 4)2
Integral : 9x + 8 = 9(x squared)/2 + 8x Differential : 9x +8 = 9
Type your answer here... 81
If you mean: x squared+9x+14 = 0 then by using the quadratic equation formula x = -2 or x = -7
2x2+9x+9 = (2x+3)(x+3) when factored
