Question

What are the possible expressions for the dimensions of the cuboids whose volumes are given below? Volume :- 12ax² + 8ax − 20a *​

Answer 1

answer...

here function of volume is in x & a

so, here Function v(a,x)=12 ax

2

+8 ax−20 a

v(a,x)=4 a(3x

2

)+4a(2x)+4a(−5)

=4x(3x

2

+2x−5)

=4a(3x

2

+5x−3x-5)

=4a[(x)(3x+5)+(−1)(3x+5)]

=(4a)(x−1)(3x+5)

so, the dimension of the cuboids will be 4a,x−1 & 3x+5
