If a polynomial has four terms, 3×3 + 5x + 6×2 + 10, which factoring method can be considered? a) Perfect-square trinomial b) Difference of squares c) Factor by grouping d) Sum of cubes [bg_collapse view=”button-red” color=”#4a4949″ icon=”arrow” expand_text=”Show Answer” collapse_text=”Hide Answer” ] Answer c) Factor by Grouping [/bg_collapse]

- x = ±√7 and x = ±√2i
- x=7 and x=5i

a. x = ±√7 and x = ±√2i

- x=+- sqrt 5 and x = ±10
- x=+- sqrt i5 and x = ±10i
- x=+- sqrt 5 and x = ±10i
- x=+- sqrt i5 and x = ±10

d. x=+- sqrt i5 and x = ±10
