Consider the steps for solving 3x^2 - 42x 9 = -5 for x by completing the square. step 1) 3x^2 - 42x = -14 step 2) 3(x^2 - 14x) = -14 step 3) 3(x^2 - 14x 49) = -14 what number should be added to the right side of the equation?

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?
