The roots of the quadratic $x^2+8x+4$ are the same as the roots of the quadratic $Ax^2+Bx+1$. What is $A+B$?

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
