beta + (alpha + beta)^2

if alpha , beta are zeroes of the polynomial x^2 + 7x + 10 then find alpha and beta . Also find the value of 1/alpha + 1/beta + (alpha + beta)^2

deepalichhabra91 Alpha = -b/a = -7/1 = -7
Alpha = -7

Beta = c/a = 10

1/(-7) + 1/10 + (-7+10)^2
-1/7 + 1/10 + 9
(-10+7+630)/70
627/70
