Question

PLEASE HURRY 9x^2 + 64 = 0 I NEED THE WORK SHOWN IN ORDER TO GET CREDIT

Answer 1

Answer:

x = ± $\frac{8}{3}$ i

Step-by-step explanation:

subtract 64 from both sides

9x² = - 64 ( divide both sides by 9 )

x² = - $\frac{64}{9}$ ( take the square root of both sides )

x = ± $\sqrt{-64/9}$ = ± $\frac{8}{3}$ i

Answer 2

Answer:

see below

Step-by-step explanation:

9x^2 + 64 = 0

9x^2 = -64

x^2 = -64 / 9  

Taking square roots of both sides:-

x = +/-  (-8/3)

x = -8i/3 , 8i/3
