Foil x2 -14x plus 46

Answer 1

factor x2-14x+46 What two numbers multiply to give 46, and (since the 14 is negative) are 14 apart?

Well, 46 only factors into [1 2 23 46], so there are no integer answers.

This calls for the quadratic formula

(-b±√(b2-4ab))/2a

(14±√(196-184)/2

(14+√(12))/2 and (14-√(12))/2

(14+3.464)/2 and (14-3.464)/2

17.464/2 and 10.536/2

8.7321 and 5.2679 are both approximations of the answers. ■
