b+c^2 There is no way to simplify that.
The like terms are sums of b terms and c terms separately 5c+2c+3c+4b 5c +2c + 4b + 3c => 10c + 4b
It is: 4b+6
b times b times b = b3 b plus b plus b = 3b
It is 2a-b simplified
It is an expression that can be simplified to: 1-4b-5c
It is: b+4 when simplified
= 4a2 + 2ab 2b2
