<h3><u>Solution:- </u></h3>
Let the number to be added be A
Now,
Transposing (−5x³+ 4x − 3 ) to other side-
Remember if there is a -ve sign before a bracket the signs of whole of the terms changes on opening bracket
Putting like terms together -
Therefore, 5x³+x²-5x +2 should be added to −5x³+ 4x − 3 to get x²− x − 1
3x-9-5x = -7
combine like terms -9-2x = -7
add 9 to both sides
-2x = 2
divide both sides by -2
x - 2/-2 = -1
x = -1
