Step-by-step explanation:
Answer:
n=0
Step-by-step explanation:
3n+4+14n=4-32n
3n+14n=-32n
17n=-32
17n+32n=0
49n=0
Remember
so
take the log of both sides
or
B is the answer
Completing the square
alrighty
minus 31 both sides
x²+12x=-31
take 1/2 of the linear coefient and square it
12 is the linear coefient
12/2=6, (6)²=36
add that to both sides
x²+12x+36=36-31
factor perfect square trinomial
(x+6)²=5
square root both sides, remember to take positive and negative root
x+6=+/-√5
so what you want to write is
x+6=√5 and
x+6=-√5
the solutions
minus 6 both sides
x=-6+√5 and -6-√5
