Question 929239: Write the equation of a quadratic whose roots are -3/7 and 2/5. Answer without fractions.
Answer by TimothyLamb(4379) (Show Source): You can put this solution on YOUR website!
(x + 3/7)(x - 2/5) = 0
xx - (2/5)x + (3/7)x - 6/35 = 0
xx - (2*7/5*7)x + (3*5/5*7)x - 6/35 = 0
xx - (14/35)x + (15/35)x - 6/35 = 0
xx + (1/35)x - 6/35 = 0

answer:
xx + 0.0285714285714x - 0.171428571429 = 0
