Answer:
Step-by-step explanation:
quadratic equation: ax² + bx + c =0
x' = [-b+√(b²-4ac)]/2a   and x" =  [-b-√(b²-4ac)]/2a  
6 = x² – 10x ; x² - 10x -6 =0
(a=1, b= - 10 and c = - 6
x' = [10+√(10²+4(1)(-6)]/2(1)  and x" = [10-√(10²+4(1)(-6)]/2(1)
x' =5+√31  and x' = 5-√31
 
        
             
        
        
        
It should be 40%, you convert 18/45 to a decimal then multiply by 100
