Answer:
x²-2x-15=0
Step-by-step explanation:
Let the roots be alpha and beta
alpha+beta=2.....1
alpha³+beta³=98.......2
(alpha+beta)³=alpha³+beta³3alpha beta (alpha+beta)
substituting the values the answer comes out to be
alpha beta= -15
Quadratic equation
x² - (sum of roots)x + product of roots
= x²-2x-15=0
the options are wrong maybe..just check with your teachers
hope it helps :)
