Hey there!! 
Recursive formula : 
... a( n ) = a ( n - 1 ) + 7 
The first term is 12 
To find the second term, we will need to substitute 2 in place of ' n ' 
2 term : 
... a( 2 ) = a ( 2 - 1 ) + 7 
... a( 2 ) = a( 1 ) + 7 
We know a( 1 ) = 12 
... a( 2 ) = 12 + 7 
... 19 is the second term and we will need to use this to find the other terms. 
Hope my answer helps! 
 
        
             
        
        
        
the discriminant formula is b^2-4ac
so plug the values from each equation into the formula and solve, the result is the value of the discriminant
if the number is negative, there are no real roots/x-int 
if it is 0 there is one real root/x-intercepts
if it is positive it has 2 real roots/x-int 
and to find the actual solutions you have to plug the values into the quadratic formula
