What are the possible expressions for the dimensions of the cuboids whose volumes are given below?(i) Volume: `3x^2-12 x` (ii) Volume: `12 k y^2+8k x-20 k`

Answer» 1) Volume=`3x^2-12x`
=3x(x-4)
Possible outcomes=3,x,(x-4)
=1,3x,(x-4)
=1,x,3(x-4)
=1,3,x(x-4)
2) Volume=`12ky^2+8ky-20k`
=k(12y^2+8y-20)
=4k(y-1)(3y+5)
one possible outcome=4k,(y-1)(3y+5)
