Question

add the following algebraic expression :-
2x² - 6x+3; -3x² – x-4; 1+2x– 3x²​

Answer 1

$\sf \Large Solution!!$

2x² - 6x + 3 + (-3x²) - x - 4 + 1 + 2x - 3x²

2x² - 6x + 3 - 3x² - x - 4 + 1 + 2x - 3x²

Now group the like terms (similar terms)!!

2x² - 3x² - 3x² - 6x - x + 2x + 3 - 4 + 1

-4x² - 5x + 0

-4x² - 5x

Answer 2

$\huge \sf { \fcolorbox{purple}{purple}{†Answer†}}$

2x² - 6x + 3 + (-3x²) - x - 4 + 1 + 2x - 3x²

2x² - 6x + 3 - 3x² - x - 4 + 1 + 2x - 3x²

Now group these

2x² - 3x² - 3x² - 6x - x + 2x + 3 - 4 + 1

$\huge \mathfrak \red{-4x² - 5x}$
