Find x intercept of:
I can clearly see three x intercepts on the graph but can not determine them mathematically. Quadratic formula and calculator give non real answer. Book says: ( -.879, 0) (1.347,0) (2.5232, 0)
The Attempt at a Solution
I am totally stuck as the quadratic gives a negative discriminant and a non real answer.... yet there are indeed three intercepts.
What am I doing wrong?
