x2 −2x − 35 = 0    let's factor this....

 

(x - 7) ( x + 5) = 0    now.....set each factor to 0

 

x  - 7 =  0                              x + 5  = 0

 

add 7 to both sides              subtract 5 from both sides

 

x = 7                                    x  =  -5

 

 

And there are the two solutions, isbella  !!!
