You must first solve the equation with absolute value, which has two possible solutions that in this case are x = 7 and x = 3. The equation is solved by applying the definition of absolute value. Then, you must solve the second-degree polynomial by applying the resolver and matching both solutions to the absolute value solutions.The result will be (b, c) = (- 10,21). I attach the correct solution.
