Factorize completely: x2−(y+z)2
...Factorize completely: x2−(y+z)2
(x - y - z)(x - y - z)
(x + y + z)(x - y - z)
(x + y + z)(x + y - z)
(x + y - z)(x - y + z)
Correct answer is B
x2−(y+z)2
Using difference of two squares (\(a^2 - b^2 = (a + b)(a - b)|)
⇒ (x + (y + z))(x - (y + z))
⇒ (x + y + z)(x - y - z)
