It is an algebraic expression

4xy

The expression has no rational factors.

2 * 2 * 5 * x * y

The prime factorization of 20xy is 22x5xxxy

(2x - 3y)(2x - 7y)

If you're looking to factor this expression, then you need to find two values that add up -20, and which multiply to make 4. Unfortunately, no such terms exist, so this expression can not be factored.

5xy (2x - 3y + 4 )

5(x^2 - 4xy + 2y^2)

Nothing is a factor BY ITSELF; you can say that one expression is a factor OF ANOTHER EXPRESSION. IF you don't specify the other expression, the question is meaningless.

I need to; factor each expression 10x + 40 = ?

2 times 2 times 5 times x times y = 20xy

This is technically a partial derivative, represented as ∂(20xy)/∂x. The way to calculate this is simple, treat y as a constant, like 20 is in this case. Therefore, the expression is simplified to 20*y*d(x)/dx. d(x)/dx is just 1, so the answer is 20y.

a common factor

There is no factor of the expression in the question.

It is a quadratic expression in x and y. Since it is not an equation it cannot be solved or represent any shape in the 2-dimensional plane.

the common factor is 1.

If an expression does not have a common factor, then it is called a "prime" expression.

An expression is in its lowest terms if the greatest common factor of the numerator and denominator is one.An expression is in its lowest terms if the greatest common factor of the numerator and denominator is one.An expression is in its lowest terms if the greatest common factor of the numerator and denominator is one.An expression is in its lowest terms if the greatest common factor of the numerator and denominator is one.

5x2 - 20xy + 10y2 = 5(x2 - 4xy + 2y2) which cannot be simplified into rational factors.
