Given that f(x) = 13x2 + 156, find x. a) x = ±2i 3 b) x = ±2i 6 c) x = ±3i 5 d) x = ±3i 6

  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

a = 11 : 4

b = 38

c = 1 for every 6

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
