    Step-by-step explanation:

    ANSWER

    Given equation:

    2x

    2

    +xy−3y

    2

    +x+ay−10=(2x+3y+b)(x−y−2)

    ⇒2x

    2

    +xy−3y

    2

    +x+ay−10=2x

    2

    +3xy+bx−2xy−3y

    2

    −by−4x−6y−2b

    ⇒2x

    2

    +xy−3y

    2

    +x+ay−10=2x

    2

    +xy−3y

    2

    +(b−4)x−(b+6)y−2b

    Comparing the coefficients of x,y and constants will get:

    b−4=1..(i)

    −(b+6)=a..(ii)

    −2b=−10..(iii)

    From eq(1), we get

    ⇒b=5

    Now put b in eq(2), we get

    ⇒−(b+6)=a

    ⇒a=−11

    From eq(3), we get

    ⇒−2b=−10

    ⇒b=5

    Hence values of a,b are −11,5
