Answer 2

Hi friend!!

α and ß are the zeroes of the quadratic polynomial ax²+bx+c

We know the relationship between zeroes and coefficients,

Sum of zeroes = -b/a

α+ß = -b/a

Product of zeroes = c/a

αß = c/a

→ 1/α + 1/ß - 2αß

→ (ß+α)/αß - 2αß

→ (-b/a)/c/a - 2(c/a)

→ -b/c - 2c/a

→ (-ba - 2c²)/ac

Hope it helps...
