Question

write a quadratic equation whose roots are -2/3, 1/3​

Answer 1

Since -1 and -3 are roots, then x-(-1) and x-(-3) are factors

 

y = 2(x+1)(x+3) is the desired quadratic equation.  

Answer 2

Answer:

x²-sum of roots×x+product of roots

Step-by-step explanation:

let -⅔ be alpha

⅓ be beta

sum of root.....alpha+beta

product of roots...alpha×beta
