Question

If a, ß are roots of 5x2 + 5x + 6 = 0 then
the value of (1 + a) (1 + ) = ( )​

Answer 1

Answer:

6/5

Step-by-step explanation:

$5x^{2} + 5x + 6 = 0$

a = 5

b = 5

c = 6

From Vieta's Formula

The sum of roots = -b/a

The product of roots = c/a

so $\alpha + \beta$ = -1

$\alpha \beta$ = 6/5

$(1+\alpha) (1+\beta)$ = 1+$\alpha$+$\beta$+$\alpha \beta$ = 1+(-1)+(6/5) = 6/5

Answer 2

Answer:

6/5

Step-by-step explanation:

Alpha+beta=-5/5=-1

Alpha.Beta=6/5

(1plus alpha) (1+beta)

1+alpha +beta +alpha.beta

1-1+6/5

6/5
