Question

plz help me to find this

Answer 1

Answer:

Step-by-step explanation:

⇒(x²)²-{(y+z)²}²

⇒Using a²-b²=(a+b)(a-b)

⇒{x²+(y+z)²}{x²-(y+z)²}

⇒Using (a+b)²=a²+2ab+b²

⇒(x²+y²+2yz+z²){x²-(y+z)²}

⇒Using a²-b²=(a+b)(a-b)

⇒(x²+y²+2yz+z²) (x+y+z) {x-(y+z)}

Final answer = (x²+y²+2yz+z²) (x+y+z) (x-y-z)
