It is an algebraic expression

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

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

2(10XY) 5(2XY) 4(5XY) 22(5XY) and so on, though not very interesting factoring

The GCF is 4xy

The expression has no rational factors.

The GCF is 4xy.

2 times 2 times 5 times x times y

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.

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.

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.

20xy2 = 225xy2 so the factors are 1 x y xy y2 2 2x 2y 2xy 2xy2 4 4x 4y 4xy 4y2 5 5x 5y 5xy 5y2 10 10x 10y 10xy 10y2 20 20x 20y 20xy 20y2

Well, the way you wrote it, you would have:(4x - 5y - 3) x 3x + 5ywhich would give12x^2 - 15xy - 9x + 5yBut, if you meant the quantity (3x + 5y), then you would have:(4x - 5y - 3) x (3x + 5y)which would give12x^2 - 15xy - 9x + 20xy - 25y^2 - 15yand combining terms12x^2 - 25y^2 + 5xy - 9x - 15y

The question doesn't nail it down; i.e., there can be several answers that satisfy the given information. Perimeter 'P' = 2 x (Length + Width) Area 'A' = (Length) x (Width) = 2 x y What is the Length, and what is the Width ? Here are five correct answers: ==> If the rectangle is (2) by (x y), A = 2xy, P = 4 + 2xy ==> If the rectangle is (2x) by (y), A = 2xy, P = 4x + 2y ==> If the rectangle is (x) by (2y), A = 2xy, P = 2x + 4y ==> If the rectangle is (1) by (2xy), A = 2xy, P = 2 + 4xy ==> If the rectangle is (0.1) by (20xy), A = 2xy, P = 0.2 + 40xy
