Answer :

The correct simplification of the given expression is (B) [tex]16x^{3} -50x^{2} -23x+30[/tex].

What is an expression?

  • An expression or mathematical expression is a finite combination of symbols that is well-formed according to context-dependent norms.

To find the correct simplification of the given expression:

  • The easiest terms to check are the first (8x)(2xΒ²) = 16xΒ³ and the last (-5)(-6) = 30.
  • This check eliminates the first choice.
  • The remaining choices differ only in the sign and coefficient of the squared term, so that is the one we need to find.
  • The squared term will be the sum of the products of factors whose degrees total 2:
  • [tex](8x)(-5x)+(-5)(2x^{2} )=-40x^{2} -10x^{2} =-50x^{2} =16x^{3} -50x^{2} -23x+30[/tex]

Therefore, the correct simplification of the given expression is (B) [tex]16x^{3} -50x^{2} -23x+30[/tex].
