Answer :
Answer:
You will be solving for X. x =4/9
Step-by-step explanation:
You start by adding 16 to both sides.
then you have 9x^2 = 16
take the square root of each side
so you are left with 9x=4
then you divide each side by 9 to find the value of x
in this case, x=4/9
Answer:
(3x-4)(3x+4)
Step-by-step explanation:
a^ 2 − b^ 2 = ( a + b ) ( a − b )
9 x 2 − 16 = ( 3 x )^ 2 − ( 4 )^2
( 3 x )^2 − ( 4 )^2 = ( 3 x − 4 ) ( 3 x + 4 )
