x(x + y-r),y(x-y + r) and z(x-y-z)

Using the distributive law

x(x + y-r)= x² + xy - xr,

y(x-y + r)= xy - y²+ yr

and

z(x-y-z) = xz - yz - z²

Now we add these terms

(x² + xy - xr) + (xy - y² + yr) + (xz -yz - z²)

Answer = x²- y²- z² + 2xy-xr + yr + xz - yz

$\huge\tt{❥Answer}$

${x}^{2} + xy - rx + xy - {y}^{2} + ry + xz \\ - yz - {z}^{2} \\ {x}^{2} - {y}^{2} - {z}^{2} + 2 xy - rx + ry + xz \\ - yz \\ {x}^{2} - {y}^{2} - {z}^{2} + 2xy - r(x + y) + z \\ (x - y)$
