Question

(x+2)^2 - (x+4)^2 factories ​

Answer 1

$\red {\huge {\underline{ \frak{Your \: answEr : }}}}$

➟ (x + 2)² - (x + 4)²

$\boxed {\bold{ {a}^{2} - {b}^{2} = (a + b)(a - b) }}$

➟ (x + 2 + x + 4)(x + 2 - x - 4)

➟ (2x + 6)(-2)

$\huge{\red{\ddot{\smile}}}$

Answer 2

(x + 2)² - (x + 4)²

(x + 2 + x + 4)(x + 2 - x - 4)

(2x + 6)(-2)
