Question

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

Answer 1

Answer:

-99x^3+33x^2+13x+41

Step-by-step explanation:

given,

99x^3-33x^2-13x-41

to find the expression that makes above as zero, I am taking -( minus) before the expression.

-(99x^3-33x^2-13x-41) = -99x^3+33x^2+13x+41

99x^3-33x^2-13x-41 + (-99x^3+33x^2+13x+41) = 0
