Question

please factorise step by step

Answer 1

Answer:

1)  3(a⁴ - 4b⁴)

=> 3[(a²)²-(2b²)²]

=> 3(a²+2b²)(a²+2b²)

2) p²-16p-80

=> p²-20p+4p-80

=> p(p-20)+4(p-20)

=> (p+4)(p-20)

3) (x²/25)-625

=> (x/5)²-25²

=> [(x/5)+25][(x/5-25)]

4) p²-2p-3

=> p²-3p+p-3

=> p(p-3)+1(p-3)

=> (p+1)(p-3)

5) x²+3x+2

=> x²+x+2x+2

=>x(x+1)+2(x+1)

=>(x+2)(x+1)

6) 6x²+x-1

=> 6x²+3x-2x-1

=>3x(2x+1)-1(2x+1)

=>(3x-1)(2x+1)

Mark it as the brainliest!!
