$(2x {}^{2} + 3x - 5) + (2x {}^{2} - 4) \\ 2x {}^{2} + 3x - 5 + 2x {}^{2} - 4 \\ = 4x {}^{2} - 9 + 3x$

Answer 2

Solution :

Given two expressions are ,

2x² + 3x - 5 and 2x² - 4

Their Sum = ( 2x² + 3x - 5 )+ ( 2x² - 4 )

= 2x² + 3x - 5 + 2x² - 4

= 2x² + 2x² + 3x - 5 - 4


= ( 2 + 2 )x² + 3x - 9

= 4x² + 3x - 9
