is there a value for h that makes it possible for the equation √(x+h)+5=0 to have any real number solution? explain

    is x+h+5 all under the square root? or just x+h?

    ok.. so you want to find a value for h that makes the expression \[\sqrt{x+h}+5=0 \implies \sqrt{x+h}=-5\] but the square root can't have a negative value. so, such h doesn't exist.

    wait, the sqroot of a number can have a negative value, the SQUARE of a number can't have a real value

    square both sides and you get x+h = 25

    that's not right mindedone, you're suggesting that h=25-x is a solution.. check by plugging back into the equation and see what you get.

    Keep in mind though that if you plug h=25-x into the original equation you get +-sqrt(25) = -5, and so the negative square root does satisfy the equation.

    you get sqrt(25) = -5

    sqrt(25) = +-5
