Question

If one root of the equation x2

+ ax + 3 = 0 is 1, then its other root is​

Answer 1

Answer:

x = -4

Step-by-step explanation:

If 1 is one of the roots then x=1 should give 0 as remainder.

therefor-:

1+a+3 = 0

a = -4

Quadratic equation is = x² - 4x+3

x²-4x+3 = (x-1)(x+4)

Hence the other root is x = -4

Answer 2

Answer:

If 1 is one of the roots then x=1 should give 0 as remainder.

therefor-:

1+a+3 = 0

a = -4

Quadratic equation is = x² - 4x+3

x²-4x+3 = (x-1)(x+4)

Hence the other root is x = -4
