Andy is solving a quadratic equation using completing the square. If a step in the process results in 169/9 = (x – 6)2, could the original quadratic equation be solved by factoring? Explain your reasoning.
Yes the equation can be solved by factoring. Using the given equation take the square root of both sides. Both 169 and 9 are perfect squares so the left side becomes plus or minus 13/3 which is rational. Six plus 13/3 is also a rational number. If the solutions of a quadratic equation are rational then the equation is factorable. Please mark a good rating and brainlest
