Answer: x= (2)/5 & x= (-2)/5

Explanation:

Factor Form:

1. Use the sum product patturn

25x^2-4=0 → 25x^2+10-10-4=0

2. Common factors from each pair

25x^2+10-10-4=0 → 5x(5x+2)-2(5x+2)=0

3. Rewrite the factored form

5x(5x+2)-2(5x+2)=0 → (5x+2)(5x-2)=0

4. Create separate equations

(5x+2)(5x-2)=0 → 5x+2=0 5x-2=0

5. Solve

5x+2=0 5x-2=0 → x=(2)/5 x=(-2)/5
