Answer 1

here's the solution. check it out. hope it helps.

Answer 2

x² + ax + β = 0 ; Roots are 8 and 2

Sum of roots = 8 + 2 = -a ; a = -10

x² + αx + b = 0 ; Roots are 3 and 3

Product of roots = 3 * 3 = b ; b = 9

x² + ax + b = 0

x² - 10x + 9 = 0

( x - 9 )( x - 1 ) = 0

Therefore ,

Roots of x² + ax + b = 0 are 1 and 9 corresponding to the 4th option
