Answer:

x ≈ - 6.49, x ≈ 12.49

Step-by-step explanation:

Given

(x - 3)² + 7 = 97 ( subtract 7 from both sides )

(x - 3)² = 90 ( take the square root of both sides )

x - 3 = ± $\sqrt{90}$ ( add 3 to both sides )

x = 3 ± $\sqrt{90}$

Then

x = 3 - $\sqrt{90}$ ≈ - 6.49 ( to the nearest hundredth )

x = 3 + $\sqrt{90}$ ≈ 12.49 ( to the nearest hundredth )
