xy + x + y + 1 is an expression, not an equation. An expression cannot be solved.
You cannot. What you have in the question is an expression. An expression cannot be proven. You need an equation (or inequality).
The expression written in the question is the rational expression.
x does not equal -1, because if x is minus 1, x plus 1 is zero and division by zero is not defined.
It is a quadratic expression and when factored is: (x+1)(x+1)
b + 1 is b plus 1 as an algebraic expression.
xy + x + y + 1 is an expression, not an equation. An expression cannot be solved.
You cannot. What you have in the question is an expression. An expression cannot be proven. You need an equation (or inequality).
The answer is b+1. Therefore the algebraic expression for this is b+1
Both - a polynomial expression, if you like.
The expression written in the question is the rational expression.
When simplified it is just: 1
(3x2 + 2x + 1)
There are 5 terms in the given expression
An algebraic expression
2m + 1
It is an expression and can be simplified to: 3d+f+1
