you have to multiply by -3
so the answers are going to be one negative one positive
and the next 5th terms are 108,-324,972,-2916,8748
Answer:

factorise out a and x :

but from general factorization:

a » x
b » 2
therefore:

You need to add all of them up then devied by how many there are
So, this is too vague but I'll solve for both quadratic formula and find the discriminant.
Quadratic formula: <span>x=<span>5+<span><span><span>√35 OR</span><span> </span></span>x</span></span></span>=<span>5−<span>√<span>35
Finding the discriminant: 141</span></span></span>
