x + x + 1 + x + 2 + x + 3 = -144x + 6 = 144x = 8x = 2
x^3 + ax + 3a + 3x^2 = (x^3 + 3x^2) + (ax + 3a) = x^2(x + 3) + a(x + 3) = (x + 3)(x^2 + a)
(x-2)(x^2+3)

The value of x in the equation -2 x plus 3 4x-3 is 3.
The equation 5X plus 4X-2-2 times2 X-1 plus 3 X plus 2 equals 2. This is a math problem.
It is 123.99
x3 + 2x2 + 3x + 6 = x2(x + 2) + 3(x + 2) = (x + 2)(x2 + 3)
11+(7-3)2=
(x + 2) = 3/x + 2 (x + 2)(x + 2) = 3 x + 2 = √3 x = √3 - 2 x = 1.732050808 - 2 x = -0.267949192 Check: -0.267949192 + 2 = 3/(-0.267949192 + 2) 1.732050808 = 3/1.732050808 1.732050808 = 1.732050808
x^2 + 3 = x^2 - (-3) = x^2 - (√-3)^2 = x^2 - (i√3)^2 = [x - (√3)i][x + (√3)i]
x^3+x^2+2x = x(x^2+x+2)
