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.
