Answer:
[tex]-2.4x^2-1.5x-11.4[/tex]
Step-by-step explanation:
[tex]-4.1x^2+0.9x-9.8\\\ 1.7x^2-2.4x-1.6[/tex]
Adding the polynomials.
We combine the like terms.
[tex](-4.1x^2+1.7x^2)+(0.9x-2.4x)+(-9.8-1.6)[/tex]
Evaluating each term separately
[tex]-4.1x^2+1.7x^2=-2.4x^2[/tex]
[tex]0.9x-2.4x=-1.5x[/tex]
[tex]-9.8-1.6=-11.4[/tex] [Two negative terms when added gives the sum with a negative sign]
Combining the terms.
[tex](-2.4x^2)+(-1.5x)+(-11.4)[/tex]
[tex]-2.4x^2-1.5x-11.4[/tex]
