Solve the following quadratic expressions by factoring. First write the expressions in completely factored form. Then write the real number solutions. [Hint: Remember to use proper notation when writing the real number solutions. For example: if the solutions are x=1 and x=4, write x=1,4 x2+15x+56=0 Real number solutions: Factored Form:   x2−x−56=0 Real number Solutions:  Factored Form: x2−36=0 Real number solutions:  Factored Form: x2−10x+25=0 Real number solutions:  Factored For
