Square Both Sides: Square both sides of the equation to eliminate the square roots.(−4h)2=(−5−5h)2−4h=−5−5h
Add Terms: Add 5h to both sides of the equation to get all h terms on one side.−4h+5h=−5−5h+5hh=−5
Check Solution: Check for any math errors and verify if the solution makes sense in the original equation.Substitute h=−5 back into the original equation:−4(−5)=−5−5(−5)20=20Since both sides are equal, there are no math errors, and the solution is correct.
