Question

v) a^2 + 2ab + b^2-z^2​

Answer 1

Step-by-step explanation:

(a+b) ^2 - z^2

= (a+b+z) (a+b-z)

Answer 2

Answer:

(a + b + z)(a + b - z)

Step-by-step explanation:

a² + 2ab + b² - z²

= (a + b)² - z² [(a + b)² = a² + 2ab + b²]

= (a + b - z) × (a + b + z) [(c² - d²) = (c + d) × (c - d)]
