Step-by-step explanation:
...............
You would use the subtraction property of equality.
The square root of 144= 12. 12 is an integer, integers are always rational since they can be written into a fraction.
-------------------------------------------------------
Equation Given :
-------------------------------------------------------
16x² = 121
-------------------------------------------------------
Take away 121 from both sides:
-------------------------------------------------------
16x² - 121 = 0
-------------------------------------------------------
Make each term a perfect square
--------------------------------------------------------
(4x)² - (11)² = 0
--------------------------------------------------------
Apply algebraic rule : a² - b² = (a + b)(a - b)
--------------------------------------------------------
(4x + 11) (4x - 11) = 0
-------------------------------------------------------
Apply zero product property :
-------------------------------------------------------
4x + 11 = 0 or 4x - 11 = 0
--------------------------------------------------------
Solve for x :
--------------------------------------------------------
4x = - 11 or 4x = 11
x = -11/4 or x =11/4
--------------------------------------------------------------------------
Answer: x = -11/4 or x = 11/4
--------------------------------------------------------------------------
