Question

The sum and product if zero's of polynomial are -2/5 and 4/3. Find the values of A,B and C, hence write the quadratic polynomial in m.

​

Answer 1

Answer:

15m^2+6m+20=0

Step-by-step explanation:

sum of the roots = -2/5

product = 4/3

solution

the quadratic polynomial whose roots are given is written as,

x^2 - (sum of the roots)x + (product of the roots)

= 0

therefore,

m^2 - (-2/5)x + (4/3) = 0

m^2 +(2/5)x + (4/3) = 0

m^2 + (6m + 20)/15 = 0

15m^2 + (6m + 20) = 0

therefore, the ans is,

15m^2 + 6m + 20
