(x - 3)(x^2 + 6)
x(3x+6) or 3x(x+2). Id recomend the second one.
3x + x + 10 + x = 5x + 10
5370
x^2 + 3x + 7 = 6x + 18 x^2 - 3x - 11 = 0
3X^2 + 9X/3X factor out 3X 3X(X + 3)/3X 3X/3X = 1, so... X + 3 is the simplest form here
(x - 3)(x^2 + 6)

x^2 + 3x + 7 = 6x + 18 x^2 - 3x - 11 = 0
As written, that's -x - 2, which is in its simplest form. 2x^2 - 3x - 2 = (2x + 1)(x - 2)
It is a singular matrix.
5x-3x+x+8 = 2x+1+x+x 3x+8 = 4x+1 3x-4x = 1-8 -x = -7 x=7 Hope that helps.
3x+5<x+11 3x<6 x<2
-x + 3x = 2x
x = 4/15
