Answer:
Step-by-step explanation:
The given expression is a polynomial expression that needs to be simplified:
Starting with: (6x-1)(6x-1) - x + 3(x+5) - 7x(x)
1. Remove the parentheses:
(6x-1)(6x-1) - x + 3(x+5) - 7x · x
2. Simplify the product inside each set of parentheses:
36x^2 - 6x - 6x + 1 - x + 3x + 15 - 7x^2
3. Remove the parentheses:
36x^2 - 6x - 6x + 1 - x + 3x + 15 - 7x^2
4. Collect like terms:
29x^2 - 10x + 16
So, the simplified expression is 29x^2 - 10x + 16.
