a= 1, b = 6, c = 8
My answer using the quadratic formula:
How do I reduce this further to get the final answer or is my answer correct? I always get confused. Thanks in advance.
yeah, the quadratic formula can be overkill at times. However, i do agree with Soroban that we are making it more complicated than it should be. Generally it helps students to visualize what to do by replacing a squared term with a single variable, but i believe that's wasting writing space. ordinarily, i'd just factor as Soroban did and cut out the middle man, but i didn't really want to shock you. you'd be surprised at some of the things students are shocked with
