How many solutions does 2x − 2x − 7 −7 have

WebExample: 2x 3 −x 2 −7x+2 The polynomial is degree 3, and could be difficult to solve. So let us plot it first: The curve crosses the x-axis at three points, and one of them might be at 2. We can check easily, just put "2" in place of "x": f (2) = 2 (2) 3 − (2) 2 −7 (2)+2 = 16−4−14+2 = 0 Yes! f (2)=0, so we have found a root!
