Answer:
The answer is : x = 9.505 and x = -1.005
Step-by-step explanation:
To solve the quadratic equation use the formula :

Where a is the coefficient of x² , b is the coefficient of x and c is the numerical term
∵ a = 18 , b = -153 and c = -172
∴ 

∴ x = 9.505 and x = -1.005
0,2 because the y intercept is th middle line so you go up the line and see what number the line goes through
