Question

find a quadratic polynomial whose zeroes are minus 1/3 and 4/5​

Answer 1

Given

Zeroes pf the quadratic equation is -1/3 and 4/5

To Find

Quadratic Polynomial

Now Let

α = -1/3  and β = 4/5

Sum of zeroes

(α + β) = -1/3 + 4/5

(α + β) = (-5+12)/15

(α + β) = 7/15

Product of Zeroes

αβ = -1/3×4/5

αβ = -4/15

General Formula

x² -(α+β)x + αβ = 0

Now up the value on formula  

x² - (7/15)x + (-4/15) = 0

x² - (7/15)x - 4/15 = 0

Taking LCM

15x² - 7x - 4 = 0

Answer

15x² - 7x - 4 = 0
