Answer:

[tex]=7x^2 - 10x -9[/tex]

Step-by-step explanation:

Given that:

=(3x2 + 5x + 11) + (4x2 – 15x – 2)

By opening brackets we get:

=[tex]3x^2 +5x +11 +4x^2 -15x -2[/tex]

Now adding like terms: constants into constants and variabe with same power of x into each other:

= [tex](3x^2 + 4x^2) + (5x - 15x) + (11-2)\\7x^2 - 10x -9[/tex]

I hope it will help you!
