3b -1
2a+5
6+7a+6b
5a³ - 4ab + 2a³ = (5+2)a³ - 4ab = 7a³ - 4ab.
depends what the value of 'a' is.
2a2+3a2 = 5a2
2a+6b
If I've read your question correctly, you need to subtract: a2 +2a -7 a2 -4a2 +5a2 -6 = 2a2 -6 Note, if x - y = z, then y = x - z; so: 2a2 -6 - (a2 -2a +1) = 2a2 -6 - a2 +2a -1 = a2 +2a -7
2a² + 6a
Add them together: 2a+5a = 7a
It is 2a-b simplified
2a + 3a + 4 = 5a + 4
11a+7b-(3b-2a)
9a + 1
3b -1
To simplify the expression 2a - 3 + 4b - 2a - b - 3 + 5, we first combine like terms. Combining the terms with 'a', we have 2a - 2a = 0. Combining the terms with 'b', we have 4b - b = 3b. Combining the constants, we have -3 - 3 + 5 = -1. Therefore, the simplified expression is 3b - 1.
