Explanation:
Multiply each term in the second bracket by each term in the first bracket as shown below.
#(color(red)(2n-3))(n^2-2n+5)#
#=color(red)(2n)(n^2-2n+5)color(red)(-3)(n^2-2n+5)#
#=(color(red)(2n)xxn^2)+(color(red)(2n)xx-2n)+(color(red)(2n)xx5)#
#color(white)(=)+(color(red)(-3)xxn^2)+(color(red)(-3)xx-2n)+(color(red)(-3)xx5)#
#=2n^3-4n^2+10n-3n^2+6n-15#
#=2n^3-7n^2+16n-15larr" in standard form"#
