Answer 1

Qual a fatoração de 25x²-1/4?

25x²-1/4 = (5x +1/2)(5x - 1/2)

Answer 2

Olá!

$\\ \displaystyle \mathsf{25x^2 - \frac{1}{4} =} \\\\\\ \mathsf{5^2 \cdot x^2 - \frac{1}{2^2} =} \\\\\\ \mathsf{\left ( 5x + \frac{1}{2} \right ) \cdot \left ( 5x - \frac{1}{2} \right )}$


Obs.: a² - b² = (a + b)(a - b).
