Question

To what expression must 99x³ – 33x² – 13x – 41 be added to make the sum zero?

Answer 1

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.
