Question

B) What are the coordinates of the roots of the equation x² + 4x + 3 = 0 ?

Answer 1

(- 3, 0 ) , (- 1, 0 )

Explanation:

the roots are the values of x where the graph crosses the x- axis

from the graph these are x = - 3 , x = - 1 , then coordinates of roots are

(- 3, 0 ) and (- 1, 0 )
