Question

The path ABC trace by the car in the above picture is represented by x²+8x+15, then find the distance between G and F

Answer 1

Given : The path ABC trace by the car in the above picture is represented by x²+8x+15,

To find  : the distance between G and F

Solution:

G and F are the point where curve crosses the x axis

Hence G and F are the zeroes

x²+8x+15 = 0

=> (x + 5)(x + 3) = 0

=> x = - 5  and x = - 3

G = (-5 , 0)

F = (-3 , 0)

Distance  between G and F  =  2
