To solve this equation you need to solve for the variable x. There are more than one way you can to this but I find substitution method to be viable.
x=10, we know this because 10/2= 5 and 5-1=4. Also 10/5=2 and 2+2=4.

Answer:
(p -3q )(p -3q )
Step-by-step explanation:
p'2 - 6pq + 9q'2
(p -3q )(p -3q )
find two values that add to give 6 and multiply to 9
p x p =p'2
-3q x p = -3pq -3 x pq = -3pq ...... -3pq - 3pq = -6pq
-3q x - 3q = 9q'2
