Question

5.
Add the product: x(x+y-n), y(x-y+r), z(x-y-2)​

Answer 1

Answer:

Here we have the expressions

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

HOPE IT HELPS

THANK YOU

Answer 2

Answer:

x(x+y-n)

The product is: x^2+xy-xn

y(x-y+r)

The product is: yx-y^2+yr

z(x-y-2)​

The product is: zx-zy-2z
