Answer:

plz mark me on brain list OK

Answer 2

Answer:

x^2 - x - 12

Step-by-step explanation:

x = -3 and 4

sum of alpha and beta = -b/a

LHS

-3+4 = 1 .....→ (I)

Again the product of alpha and beta = c/a

LHS

-3*4= -12 .....→(ii)

Now, sum = 1 = -b/a

product = -12 = c/a

a = 1 ; b = -1 ; c = -12

equation is

x^2 - x - 12
