Answer:

C. ±4/5

Step-by-step explanation:

25x² = 16

25x² - 16 = 16 - 16

25x² - 16 = 0

25x² + 20x - 20x - 16 = 0

(25x² + 20x) + (- 20x - 16) = 0

5x(5x + 4) - 4(5x + 4) = 0

(5x - 4)(5x + 4) = 0

5x - 4 =0

5x + 4 = 0

[tex]x=-\frac{4}{5}[/tex]

[tex]x=\frac{4}{5}[/tex]

± is a symbol which represents addition and subtraction.
