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 = ± [tex]\sqrt{90}[/tex] ( add 3 to both sides )
x = 3 ± [tex]\sqrt{90}[/tex]
Then
x = 3 - [tex]\sqrt{90}[/tex] ≈ - 6.49 ( to the nearest hundredth )
x = 3 + [tex]\sqrt{90}[/tex] ≈ 12.49 ( to the nearest hundredth )
