The simplified expression is 3x² - 6x + 14.
What is the expression?
We want to simplify the expression (3x² + 4x - 8) + 2(11-5x):
First, distribute the 2 to both terms inside the parentheses:
= 3x² + 4x - 8 + 22 - 10x
Now, combine like terms:
= 3x² - 10x + 4x - 8 + 22
Combine the x terms
= 3x² - 6x + 22 - 8
Combine constants:
= 3x² - 6x + 14
So, the simplified expression is 3x² - 6x + 14.
