Question

What are the solutions? 16x2 + 9 = 0 (1 point). .

Answer 1

Answer:

A. $-\frac{3}{4}i,\frac{3}{4}i$

Step-by-step explanation:

16x² + 9 = 0

16x²= -9 (subtract 9 from both sides)

16x²/16= - 9/16  (divide 16 from both sides)

x² = - 9 / 16    (we have to find the square root of both sides)

We know that √( -1 ) = i.

Answer:

x 1 = - 3/4 i

x 2 = 3/4 i

So therefore the answer is $-\frac{3}{4}i,\frac{3}{4}i$ (A. $-\frac{3}{4}i,\frac{3}{4}i$).

Plus I put A. $-\frac{3}{4}i,\frac{3}{4}i$ on my test and got it correct.

Answer 2

16 x² + 9 = 0
16 x² = - 9   / : 16  ( divide both sides by 16 )
x² = - 9 / 16    ( we have to find the square root of both sides )
We know that √( -1 ) = i.
Answer:
x 1 = - 3/4 i
x 2 = 3/4 i
