Question

which equation has only two solutions: x = 3 and x = -3

A.) x^2 = 9
B.) x^2 = 6
C.) x^3 = 9
D.) x^3 = 27

Answer 1

Answer:

a

Step-by-step explanation:

Answer 2

Answer:

A

Solutions:

If x = 3

A.) 3² = 3 × 3 = 9 (This is correct)

B.) 3² = 3 x 3 = 6 (This is incorrect) (Real answer = 9)

C.) 3³ = 3 x 3 x 3 = 9 (This is incorrect) (Real answer = 27)

D.) 3³ = 3 × 3 × 3 = 27 (This is correct)

If x = -3

A.) -3² = -3 × (-3) = 9 (This is correct)

B.) -3² = -3 x (-3) = 6 (This is incorrect) (Real answer = 9)

C.) -3³ = -3 x (-3) x (-3) = 9 (This is incorrect) (Real answer = -27)

D.) -3³ = -3 × (-3) × (-3) = 27 (This is incorrect) (Real answer = -27)

So, the answer is A
