Question

Given that f(x) = 13x2 + 156, find x. A) x = ±2i 3 B) x = ±2i 6 C) x = ±3i 5 D) x = ±3i 6

Answer 1

Answer:

  A)  x = ±2i√3

Step-by-step explanation:

We presume you want to find x such that f(x) = 0.

Divide by 13:

  x² + 12 = 0

Subtract 12:

  x² = -12

Take the square root:

  x = ±i√12 = ±2i√3
