If one of the zeros of 3x^2+5x+γ=0 is 4 times the other, then find the zero and value of k
Natalija [7]

Answer:

Step-by-step explanation:

Let α be one of the zeros of the polynomial.

Other = 4α

α + 4α = - Coefficient of x / Coefficient of x² = -5/3

5α = -5/3

α = -5/3*5

α = -1/3

α * 4α = Constant term/Coefficient of x²

4α² = k / 3

4*(\frac{-1}{3})^{2}=\frac{k}{3}\\\\4*\frac{1}{9}=\frac{k}{3}\\\\4*\frac{1}{9}*3=k\\\\4*\frac{1}{3}=k\\\\k=\frac{4}{3}
