Square Both Sides: Square both sides of the equation to eliminate the square roots.(−9g)2=(−10g−10)2−9g=−10g−10
Add G Terms: Add 10g to both sides to get all the g terms on one side.−9g+10g=−10g+10g−10g=−10
Check Solution: Check the solution by substituting g=−10 back into the original equation to ensure both sides are equal.−9(−10)=−10(−10)−1090=100−1090=90Both sides are equal, so g=−10 is a valid solution.
