${x}^{2} + 3x - 10 = 0$

It is in the form of quadratic equation .eg->${ax}^{2} + bx +c= 0$

So,we factorise it to find roots:-

${x}^{2} + 5x - 2x - 10 = 0$

$= > x(x + 5) - 2(x + 5) = 0$

$= > (x - 2)(x + 5) = 0$

$= > x - 2 = 0$

$\bold{= > x = 2}$

$= > x + 5 = 0$

$\bold{= > x = - 5}$

Therefore,The roots are:(2,-5)
