Answer:
You can take out anything that is a perfect square
Step-by-step explanation:
For Example, a perfect square would be considered
64
36
to get a perfect square you multiply a number by itself
for example,
8 x 8 = 64
6 x 6 = 36
Let the number equal x:
4 times x = 4x then 3 subtracted from that is 4x-3
4x-3 = 17
Add 3 to both sides:
4x = 20
Divide both sides by 4:
x = 5
Answer: X = 5
