2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
To work out the expression (3x^2 - 6x), you can factor it. Start by identifying the greatest common factor (GCF) of the terms, which is (3x). Factoring this out gives you (3x(x - 2)). Thus, the expression can be rewritten as (3x(x - 2)).
2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
3x + 8
2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
It is: 2x2 + 25/3x - 35/9 remainder -46/9
It is an expression that can be simplified to 4x
To simplify the expression (7x + 3x - 4x + 4), combine the like terms for (x). This gives ( (7x + 3x - 4x) + 4 = 6x + 4). Therefore, the simplified expression is (6x + 4).
To simplify the expression (9x + 4y - 6x - 5y), combine like terms. For the (x) terms, (9x - 6x = 3x), and for the (y) terms, (4y - 5y = -1y) or (-y). Therefore, the simplified expression is (3x - y).
