HEY!!
No special method is followed to solve the equation (r – 20) (r + 17) = 0.
It is solved only thorough the concept, if product of two different numbers is zero, then one must be zero.
Now, (r – 20) (r + 17) = 0 implies that
r – 20 = 0 or r + 17 = 0
r = 20 or r = –17
r = 20 or –17

r-20=0 so r=20 or r^17=0so r=0
