    Answer:

    answer is x=5 ,x=-2

    Step-by-step explanation:

    we have x^2-3x-10

    x^2-5x+2x-10

    here -3x is fractorized as -5x and +2x

    then we get commen x from 1st two terms and 2 commen from last two terms

    x(x-5)+2(x-5)

    now (x-5) (x+2)

    therefore x-5=0 x+2=0

    x=5 and x= -2

    hence solved
