216 = 6s^2
can be solved in the following manner.
216/6=s^2
36 = s^2
sqrt(36) = s
flip for better overview
s = 6
the length of each side is 6 inches. :)

Answer:
Step-by-step explanation:
make one side equal to zero:
find two factors that multiply to -36 and add to -5 (-9 & 4)
factorise
solve for x
Answer:
(n + 1)(3n + 7)
Step-by-step explanation:
3n² + 10n + 7
Consider the factors of the product of the n² term and the constant term which sum to give the coefficient of the n- term.
product = 3 × 7 = 21 and sum = + 10
The factors are + 3 and + 7
Use these factors to split the n- term
3n² + 3n + 7n + 7 ( factor the first/second and third/fourth terms )
3n(n + 1) + 7(n + 1) ← factor out (n + 1) from each term
= (n + 1)(3n + 7) ← in factored form
