In each of the following cases, let's multiply and find their product. xyz, (x^2y - y^2x + z^2y)

Multiply and find their product: xyz, ( x^2y-y^2x+z^2y )

Let's find the product by formulas: (2x - y + 3z) (2x + y + 3z)

Find ( 7x^2 - y^2) xx (x-y).

A circle through the common points of the circles x^(2) + y^(2) - 2x - 4y + 1 = 0 and x^(2) + y^(2) - 2x - 6y + 1 = 0 has its centre on the line 4x - 7y - 19 = 0 . Find the centre and radius of the circle .

Let's find the product of the following:- 8x^2, 2y^2

Multiply the algebraic expressions ans find the product: x^2(x^2+x^2y+xy^2 )
