Best ResponseYou've already chosen the best response.2Which means that 2x+6 could be either positive or negative 24, because: 24 = 24 and 24=24, so: (2x+6) = 24 or (2x+6) = 24

Best ResponseYou've already chosen the best response.1\(2x + 6 = 24\) \(\sqrt{(2x + 6)^2}= 24\) \((2x + 6)^2 = 24^2\) \(4x^2 + 24x + 36 = 576\) \(4x^2 + 24x  540 = 0\) \(4(x^2 + 6x  135 = 0\) \(x^2 + 6x  135 = 0\) \(x^2 + (15  9)x  135 = 0\) \(x^2 + 15x  9x  135 = 0\) \(x(x + 15)  9(x + 15)\) \((x + 15)(x  9) = 0\) \(x = \{15, 9\}\)
