c-2b
They are terms of an algebraic expression that can be simplified to: 2b+2c
2b + 2c or 2(b + c)
(5c - 2)(c +1)
It is an equation in three unknown variables.
c-2b
The like terms are sums of b terms and c terms separately 5c+2c+3c+4b 5c +2c + 4b + 3c => 10c + 4b
4b
4b - 2c is an expression, which is equal to 2(2b - c)
a + 2b = c a = c - 2b
2a + 4b + 8c = 2(a + 2b + 4c) You could also continue by factoring the inside of the parentheses a bit: 2a + 4b + 8c = 2(a + 2b + 4c) = 2(a + 2[b + 2c])
c2 + 5c + 6 = (c + 2)*(c + 3)
They are terms of an algebraic expression that can be simplified to: 2b+2c
If: a = 2b+c Then: a-c = 2b And: b = (a-c)/2
a = 2b + c then a - 2b = c ie c = a - 2b
2s-2b= a+b+c-2b simplified that would be a+c-b.
3ab + 3ac + 2b2 + 2bc = 3a(b + c) + 2b(b + c) = (3a + 2b)(b + c)
