Question

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

Answer 1

9x^2=4

/9 /9

x^2=4/9

sqrt both sides

x=+/-
`√(4/9)`

x=+/-(
`(√(4) )/(√(9) )`)

x=+/-2/3

Answer:

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

Answer 2

x = ± 2/3

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
