Answer:

[tex]-15x^2-21x-11[/tex]

Step-by-step explanation:

We need to find the value of [tex](4x^2 -6x +7)+(-19x^2 -15x -18)[/tex].

We can find it as follows :

[tex](4x^2 -6x +7)+(-19x^2 -15x -18)=4x^2 -6x +7-19x^2-15x-18\\\\=4x^2-19x^2-6x-15x+7-18\\\\=-15x^2-21x-11[/tex]

So, the value of the given expression is equal to [tex]-15x^2-21x-11[/tex].
