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

Find the product of (5x - y +z) (5x - y +z)

Let's express the following in the product from using formula. (x+y-z)^2 - (x-y+z)^2

Let's find value of : (x - y)a + (y - z) b + (z -x)c if a = x^2 + xy + y^2,b = y^2 + yz + z^2, c = z^2 + zx + x^2

Let us simplify using formula:- (x -y) (x^2 + xy + y^2) + (y - z) (y^2 + yx + z^2) + (z - x) (z^2 + zx + x^2)

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

Let's write the value of x^3 - y^3 -z^3 - 3xyz if x = y + z

Let's find the product by successive multiplication____ (frac(x^2)(y^2) + frac(y^2)(z^2)), (frac(y^2)(z^2) + frac(z^2)(x^2)), (frac(z^2)(x^2) + frac(x^2)(y^2))

Let's find , what must be subtracted from -11x - 7y - 9z to get - 7x + 3y - 5z

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

If A = [(1,2,-3),(2,3,2),(3,-3,-4)] , find A^(-1) and hance solve the system of linear equations: x + 2y - 3z = -4, 2x + 3y + 2z = 2, 3x - 3y -4z = 11
