Question 86645
Question:


simplify (x is the letter NOT multiply)
(2x2 - 3) + (3x2 + 2x - 1) + (-2x3 - 2x2 + 2x) + (6x - 3)


Answer



(2x2 - 3) + (3x2 + 2x - 1) + (-2x3 - 2x2 + 2x) + (6x - 3)


==> 2x^2 - 3 + 3x^2 + 2x - 1 + -2x^3 - 2x^2 + 2x + 6x - 3



Collect the like terms....


==> 2x^2 - 2x^2 + 3x^2    + -2x^3  + 2x  + 2x + 6x - 1 - 3 - 3



==> -2x^3 + 3x^2 + 10x - 7 


Which is the simplified form.


Hope you found the explanation useful.
