Answer 2

$\large\mathfrak \pink{Solution:-}$

$\underline \mathbb{FORMULA:-}$

i) a² - b² = (a + b)(a - b)

$\underline \mathbb{BY  \: THE  \: PROBLEM:-}$

4x² - 169y²

=(2x)² - (13y)² -------- (Taking both the terms in whole square.)

=(2x - 13y)(2x + 13y)-----------(By Formula {i} )

$\underline \mathbb{ANSWER:-}$

(2x - 13y)(2x + 13y)
