8(x + 1)
It is an expression that can be simplified to: -8x-4
x2 + 8x + 15 = (x + 3) (x + 5).
It is: 29+8x
This is not factor-able.
It is an algebraic expression in the form of: 8x+10
8(x + 1)
The expression simplifies to -8x.
64
It is not possible to give a sensible answer to this question. The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one expression, 8x+16, in the question!
An algebraic expression
It is an expression that can be simplified to: -8x-4
An algebraic expression
18 + 8x + x = = 18 + 9x = 9(2 + x) which is the factored form of the expression.
8x^4
-8x - 10 - 20 = -8x - 30
That does not factor neatly.
