y=x^2+5x-6

 

The x intercepts occur where y  = 0   ....so....

 

0   = x^2 + 5x - 6      factor

 

0  =  ( x -1) ( x + 6)

 

Set  both factors to  0.....solve for x

 

x -  1  =  0                                               x +   6   =  0

add 1 to both sides                                subtract 6 from both sides

x =  1                                                      x =  -6

 

And those are the two x intercepts
