Answer:
[tex]G+P=-5t^2+2t-3[/tex]
Step-by-step explanation:
The given functions are
[tex]G=3t^2-5t+6[/tex]
[tex]P=-8t^2+7t-9[/tex]
We need to find the value of G+P.
Add both functions.
[tex]G+P=(3t^2-5t+6)+(-8t^2+7t-9)[/tex]
[tex]G+P=3t^2-5t+6-8t^2+7t-9[/tex]
On combining like terms.
[tex]G+P=(3t^2-8t^2)+(-5t+7t)+(6-9)[/tex]
[tex]G+P=(-5t^2)+(2t)+(-3)[/tex]
[tex]G+P=-5t^2+2t-3[/tex]
Therefore, the required function is [tex]G+P=-5t^2+2t-3[/tex].
