Q. Find both solutions to the equation.100+(n−2)2=116
Isolate squared term: Start by isolating the squared term on one side of the equation.Subtract 100 from both sides of the equation to get:100+(n−2)2−100=116−100This simplifies to:(n−2)2=16
Take square root: Take the square root of both sides of the equation to solve for n−2.(n−2)2=±16This gives us two possible solutions because the square root of a number can be both positive and negative:n−2=±4
Solve for n: Solve for n by adding 2 to both sides of each equation.For the positive root:n−2+2=4+2n=6For the negative root:n−2+2=−4+2n=−2
