Answer:
Option C is correct.
Simplified expression of \((10x^2 -8x -1) + (4x^2-8x -5)\) is, \(14x^2 -16x -6\)
Step-by-step explanation:
To simplify the expression: \((10x^2 -8x -1) + (4x^2-8x -5)\)
First remove the parenthesis, we have;
\(10x^2 -8x -1 + 4x^2-8x -5\)
Like terms defines as the terms whose variables are the same.
Combine like terms;
\((10x^2+4x^2) + (-8x -8x) + (-1-5)\)
Simplify:
\(14x^2 -16x -6\)
therefore, the simplified given expression is., \(14x^2 -16x -6\)
