Question

5.
Add the product: x(x+y+r), y(x+y+r), z(x–y–z)​

Answer 1

Answer:

Step-by-step explanation:

Consider the given polynomials,

⇒x(x+y−r),y(x−y+r),z(x−y−z)

Now,

⇒x(x+y−r)+y(x−y+r)+z(x−y−z)

⇒(x 2+xy−xr)+(yx−y 2+yr)+(zx−zy−z 2)

⇒x 2−y 2−z 2+xy−xr+yx+yr+zx−zy

Hence, this is the answer.
