To what expression must 99x3 – 33x2 – 13x – 41 be added to make the sum zero?
उत्तर
In order to find the solution, we will subtract 99x3 – 33x2 – 13x – 41 from 0
Required expression is 0 – (99x3 – 33x2 – 13x – 41) = 0 – 99x3 + 33x2 + 13x + 41
= –99x3 + 33x2 + 13x + 41
So, If we add –99x3 + 33x2 + 13x + 41 to 99x3 – 33x2 – 13x – 41, then the sum is zero.
