Answer 1

2.a.2x+8
   b.-4a³+8ab²
   c.2x²y-8
   d.15x+10y
    e.-p⁴+3p³

3a.(6-x)(6x-1)
     =6(6x-1)-x(6x-1)
     =36x-6-6x²+x
     =36x+x-6-6x²
     =37x-6-6x²
 b.(p+5)(2p-5)
    =p(2p-5)+5(2p-5)
    =2p²-5p+10p-25
    =2p²+5p-25
 c.(5+2m)(m-8)
    =5(m-8)+2m(m-8)
    =5m-40+2m²-16m
     =5m-16m-40+2m²
     =-11m-40+2m
