What are the zeros of the quadratic function f(x) = 8x2 – 16x – 15?



x = –1 – Startroot 2 EndRoot and x = –1 + Startroot 2 EndRoot


x = –1 – StartRoot StartFraction 15 Over 8 EndFraction EndRoot and x = –1 + StartRoot StartFraction 15 Over 8 EndFraction EndRoot


x = 1 – StartRoot StartFraction 23 Over 8 EndFraction EndRoot and x = 1 + StartRoot StartFraction 23 Over 8 EndFraction EndRoot


x = 1 – StartRoot 7 EndRoot and x = 1 + StartRoot 7 EndRoot
