To simplify the expression ((1x^2 - 2x + 4) + (2x + 1) - (x^2 + 5)), first combine like terms. The (x^2) terms give (1x^2 - 1x^2 = 0). The (x) terms yield (-2x + 2x = 0), and the constant terms combine to (4 + 1 - 5 = 0). Thus, the simplified expression is (0).
2x
2x plus 5x simplified is 7x.
2x + 4x + 3 = 6x + 3
6x + 9 + 2x = 8x + 9
5x - 8a + 4a - 2x + a = 3x - 3a
x - 2x + 3 = 3 - x
3x + 7y
Simplify 4x + 3 = 2x + 8 2x = 5 x =2½
x(x + 2)
6x-2y
You can factor it, if you consider that simpler.
6x plus 4y
