This is josh’s solution for the equation x^2 - 6x - 7 = 0: josh's work: is there an error? which step is wrong? x^2 -6x - 7 = 0 mark the row where the error happens. x^2 -6x = 7 given equation. x^2 - 6x + 9 = 7 + 9 step 1) (x - 3)^2 = 16 step 2) x - 3 = 16 x - 3 = -16 step 3) x = 19 x = -13 step 4) step 5) is josh's solution correct? how do you know? give your reason. any would be gladly accepted.
