solve this please urgent​

Answer 1

Answer:

1) a⁴-b⁴

=(a²+b²)(a²-b²)

=(a²+b²)(a+b)(a-b)

2)a⁴-2a²b²+b⁴

=(a²)²-2.a².b²+(b²)²

=(a²-b²)²

3)I cant do

4)x⁸-1

=(x⁴)²-(1)²

=(x⁴+1)(x⁴-1)

=(x⁴+1){(x²)²-(1)²}

=(x⁴+1)(x²+1)(x²-1)

=(x⁴+1)(x²+1){(x)²-(1)²}

=(x⁴+1)(x²+1)(x+1)(x-1)

5)I cant do

6)x⁴-625

=(x²)²-(25)²

=(x²+25)(x²-25)

=(x²+25){(x)²-(5)²}

=(x²+25)(x²+5)(x²-5)
