QuestionEstimate the root(s) of the function $f(x)=x^{2}+x-55$ by integers. Seperate your answer(s) by commas. The roots are $\approx$ $\square$ Remark: When choosing a number to start Newton's method, it is important that you choose a number close to the root that you're trying to estimate (or else, Newton's method might end up giving you an estimate of the wrong root).
