Solve for x in the equation x2+4x-4=8

2. 2•2+2•4-4=8. First add 4 to 8 then you have 2x+4x=12. Then divide by 6 and you get 2.

X²+4x-4-8=0
x²+4x-12=0
(x+6)(x-2)=0
x=-6 or 2

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?
