Question

If the roots of the equation a x square +bx+c=0 are -1 , -2 ,then find a:b:c​

Answer 1

Step-by-step explanation:

a-b+c=0

4a-2b+c=0

a:b:c

1/4:1/2:1/1

Answer 2

Step-by-step explanation:

ax^2 + bx + c = 0

Roots : -1, -2 .

ax^2 + bx + c = (x+1)(x+2)

(x+1)(x+2) = 1x^2 + 3x +2

here, a= 1, b= 3 and c = 2.

Then a:b:c = 1:3:2
