Here we are given the expression:
Now let us equate it to zero to find x first,
Now subtracting 52 from the other side,
taking square root on both sides,
So we will get two values of x as ,
Now we can write square root -1 as i,
So our factors become,
Answer:
The final factored form becomes,
Answer:
= 8n - 11
Step-by-step explanation:
There is a common difference between consecutive terms in the sequence, that is
5 - (- 3) = 13 - 5 = 21 - 13 = 8
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 3 and d = 8 , thus
= - 3 + 8(n - 1) = - 3 + 8n - 8 = 8n - 11 ← note this is the second option, that is
f(n) = - 3 + 8(n - 1)
