    Step-by-step explanation:

    • x^2+10x=0

    (x+10)(x-0)=0

    x=-10 and x=0

    • x=-10 in x^2+10x+h=h

    (-10)^2+10(-10)+h=h

    100-100+h=h

    0=0

    • x=0 inx^2+10x+h =h

    0^2+10(0)+h=h

    0+h=h

    0=0

    I think,you miss some numbers

    if you don’t miss some numbers, this solution is no solution
