Answer 1

c) 2*[6*(3x+2)-23]-86
=2*[6*(3x+2)-23-43]
=2*(18x+12-23-43)
=2*(18x-54)
=2x18(x-3)
=36(x-3)

d) 2*[7*(2x+1)-11]+16-36
=2*[7*(2x+1)-11]-20
=2*[7*(2x+1)-11-10]
=2(14x+7-11-10)
=2(14x-14)
=2x14(x-1)
=28(x-1)

e)5*[6*(2x+5)-12]-140-10
=5*[6*(2x+5)-12]-150
=5*[6*(2x+5)-12-30]
=5(12x+30-12-30)
=5x12(x-1)
=60(x-1)

f)3*[2*(3x+4)+14]-90-30
=3*[2*(3x+4)+14]-120
=3*[2*(3x+4)+14-40]
=3*(6x+8+14-40)
=3(6x-18)
=3*6(x-3)
=18(x-3)
