Question

. In a class of (4x2 + x -8) students, (2x + 16) play football and the rest play
basketball. How many of them play basketball?

Answer 1

4x^2+x-8-(2x+16)

=4x^2+x-8-2x-16

=4x^2-x-24

Answer 2

$given \: the \: no \: of \: students \: = 4x {}^{2} + x - 8 \\ \\ the \: students \: play \: football = 2x + 16 \\ \\ the \: studens \: \: play \: volley \: ball = 4x {}^{2} + x - 8 - (2x + 16) \\ = 4x {}^{2} + x - 8 - 2x - 16 \\ = 4x {}^{2} - x - 24 \\ \\ is \: your \: answer$
