Question

Find the product of 24a² (1-2a) and
evaluate its value if.a
3.​

Answer 1

Answer:

Given, 24a^2 ( 1 - 2a )

and

a = 3

so

$24a ^{2} (1 - 2a) \\ \\ = 24a ^{2} - 48a ^{3} \\ \\ now \: a = 3 \\ \\ putting \: back \: the \: value \: of \: a \\ \\ 24(3) ^{2} - 48(3) ^{3} \\ \\ = 24 \times 9 - 48 \times 27 \\ \\ = 216 - 1296 \\ \\ = - 1080$
