Ok, so here your being asked to solve 6x2 + 5x = -7 
The procedure that I did was using this formula it led me to get the following:
Using the formula: 
 x = -(-5) ± √(-5)² - 4(6)(-6)/ 2(6) 
 x = 5 ± √ 25 + 144 / 12 
 x = 5 ± √ 169 / 12 
 x = 5 ± 13/12 
 x1 = 5 + 13/12 
 x1 = 18/12 
 x1 = 3/2 
 x2 = 5 - 13/12 
 x2 = -8/12 
 x2 = - 2/3 
Hope this helped :)
