Question

(X-5)^2-9=0 i need help

Answer 1

Answer: {8, 2}

Step-by-step explanation: Move the -9 to the right side.

So we have (x - 5)² = 9.

Square rooting both sides, we have x - 5 = ± 3.

Always use plus or minus when square

rooting both sides of an equation.

So either x - 5 = 3 or x - 5 = -3.

Solving each equation from here, our solution is {8, 2}.
