Entrance Examination No 2 Grade 9 Mathematics

The square root of α⁸ is

• α
• α²
• α⁴
• α⁶

(α − 1)(α + 1) = 

• α² + 2α − 1
• α² − 2α − 1
• α² + 1
• α² − 1

Solve by factoring: x² + 3x - 18 = 0

• x = -3 and x = 6
• x = 3 and x = -6
• x = -9 and x = 2
• x = 9 and x = -2

Simplify the expression:

• -15 + 8√9
• 9
• 2 + 8√3 + 6√6
• 9 + 14√3
