Priya wants to sketch a graph of the polynomial f defined by f(x) = x³ + 5x² + 2x - 8. She know f(1) = 0, so she suspects that (x-1) could be a factor of x³ + 5x² + 2x - 8 and writes (x³ + 5x² + 2x - 8) = (x-1)(?x² + ?x +? ) 1. Draw a box diagram
2. Write f(x) as the product of (x-1) and another factor
3. Write f(x) as the product of three linear factors
