Solve (x - 3)² = 5
Give your solutions correct to 3 significant figures.

Answer:
x=5.24 x=0.764
Step-by-step explanation:
(x - 3)² = 5
Take the square root of each side
sqrt((x - 3)²) = sqrt(5)
x-3 = ±sqrt(5)
Add 3 to each side
x-3+3 = 3±sqrt(5)
x = 3±sqrt(5)
x = 3+sqrt(5) x = 3-sqrt(5)
x=5.23606 x=0.76393
To 3 significant figures
x=5.24 x=0.764
