3x + 2 = 3x + 6 This is not possible.
4x2+3x+6+5x+3x+6 = 4x2+11x+12 when simplified
I think you mean (3x ± 1)^2 = (3x+1)(3x-1)?
The Abelian property or commutativity.
9x+3
No. It is 9x, which is a monomial.
3x + 2 = 3x + 6 This is not possible.
4x2+3x+6+5x+3x+6 = 4x2+11x+12 when simplified
3x + 11
The equivalent expression of 3x-9 plus 3x plus 5 is negative 4.
3x-3x+4x^2+8x=4x^2+8x
6x + 8
6x
It is equivalent to: 3x+6+5 = 3x+11
