Answer 2

GIVEN :–

• a and b are the zeroes of the polynomial 5x² - 12x - 3 = 0 .

TO FIND :–

• Value of (1/a) + (1/b) = ?

SOLUTION :–

▪︎We know that –

• Sum of roots = -(coffieciant of 'x')/(coffieciant of x² )

=> a + b = -(12)/5

=> a + b = - 12/5

• Product of roots = (constant term)/(coffieciant of x²)

=> (a)(b) = -(⅗)

=> a.b = - (⅗)

▪︎ Now Let's find –

= (1/a) + (1/b)

= (a + b)/(a.b)

= [-(12/5)]/(3/5)

= - (12/3)

= -4

▪︎ Hence , Value of (1/a) + (1/b) = -4
