Question

What are the solution(s) to the quadratic equation 9x^2 = 4?

Answer 1

Answer:

x = ± 2/3

Step-by-step explanation:

9x^2 = 4

Divide each side by 9

9/9x^2 = 4/9

x^2 = 4/9

Take the square root of each side

x = ±sqrt(4/9)

x = ± 2/3

Answer 2

9x^2=4

/9       /9

x^2=4/9

sqrt both sides

x=+/-$\sqrt{4/9}$

x=+/-($\frac{\sqrt{4} }{\sqrt{9} }$)

x=+/-2/3

Answer:

x=2/3, x=-2/3
