If that's 6x + 10, that factors to 2(3x + 5)
To simplify the expression (4x + 6x), you combine like terms by adding the coefficients of (x). This gives you (4 + 6 = 10), so the simplified expression is (10x).
If that's -9 - 6x + 9, it simplifies to -6x
6x + 9 + 2x = 8x + 9
12x^2+10
6x^2
(3x - 30)(x + 8) can also simplify to 3(x - 10)(x + 8)
6x-2y
12
7x + 7 + 6x - 9 = 13x - 2
Simple,its just like this: 6x+1+7-3 =6x+8-3 =6x+5
6x - 5 -5 = 0 6x -10 = 0 +10=+10 6x=10 x= about 1.4
If you mean 'simplify': (3x + 5)/15 I simply divided the coefficients (numbers) by 2.
