2
It is an expression that can be simplified to: 4a+2
5
The coefficient is the number in front of the variable a, or 5.
5a + 3 + (2a - 2) + a= 5a + 3 + 2a - 2 + a= 8a + 1
It is the 5 in 5a+2
2
2 (or + 2)
It is an expression that can be simplified to: 4a+2
5
The coefficient is the number in front of the variable a, or 5.
5a + 3 + (2a - 2) + a= 5a + 3 + 2a - 2 + a= 8a + 1
what is equivalent to (x plus 4)2
2*5k or 10k are equivalent.
2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8
2 + pq
As stated it is just an algebraic expression. However, if we equate it to zero then it can be solved. 2a2 + 5a + 2 = 0 This can be factored (2a + 1)(a + 2) = 0 This means that (2a + 1) = 0 or (a + 2) = 0 Then either 2a = -1 : a = -1/2 or a = -2
