6E.1 for Textbook

Postby Allan Nguyen 2G » Thu Jan 28, 2021 12:03 am

Hello, this is a really minor problem but for 6E.1 in the textbook, the answer in the solutions manual puts in the c value for the quadratic equation as positive. Are you supposed to do that or am I doing something wrong? I put a screenshot of my work and the answer in the solution manual for comparison. I circled the thing I'm talking about in my work. Thanks in advance!

They simply factored out that negative. Your set up is correct and will get the same answer
