The value of c is 
Explanation:
Given that the trinomial is 
We need to determine the value of c such that the trinomial is a perfect square.
The value of c can be determined using the formula,

From the trinomial, the value of b is given by

Substituting the value of b in the above formula, we have,

Squaring both the numerator and denominator, we have,

Thus, the value of c is
which makes the trinomial a perfect square.
Well the lowest common multiple (LCM) is 2.2*5, which is 11. Hope this helps and give brainliest if it does, thanks!
