There is no factor of the expression in the question.
a + b + 4 is in its simplest form.
I don’t know
That expression can not be factored.
8(a + 3)
As written, this expression equals 22x + 3, which doesn't factor neatly. Make sure you copied it correctly.
(b + 3)(a + c)
(a + 2b)(c + 2d)
This expression can not be factored. It is already in it's simplest state.
This is an expression and you do not solve an expression, but you can factor this one.X2 + 3X4X2(1 + 3X2)========
