Answer:

3x² - 17

Step-by-step explanation:

  • Simplifying the expression

[tex] \tt \: (4x {}^{2} + 3) + ( - x {}^{2} - 20) [/tex]

  • Remove any parantheses that aren't needed.
  • We know that if there's a parentheses preceded by a plus sign (+), the expression remains the same.

[tex] \tt \: = 4x {}^{2} + 3 - x { }^{2} - 20[/tex]

  • Now, combine like terms then proceed calculating the difference

[tex] \tt \: = 3x {}^{2} + 3 - 20 \\ \\ \tt \orange{ = 3x {}^{2} - 17}[/tex]

Therefore, 3x² - 17 is the answer.
