hey frnd.....
just solve both the equation and see which factor is common....
{x}^{2}  + 7x + 10 \\  {x}^{2}  + 5x + 2x + 10 \\ x(x + 5) + 2(x + 5) \\ (x + 2)(x + 5) \\
and
 {x}^{2}  - 3x - 10 \\  {x}^{2}  - 5x  + 2x  -  10 \\ x(x - 5)    + 2(x - 5) \\ (x + 2)(x - 5)
now they both have (x+2) as common solution....
so it's common factor
(4) x+2 is correct option

HOPE THIS HELP YOU ☺☺❤❤❣❣❣❣
