The first set of parentheses is unnecessary, so it can just be removed.
To remove the second set of parentheses, you must distribute the negative sign that is to its left. It changes every sign inside the parentheses.

Answer:
The equation of the line tangent to the graph of f at x = -1 is .
Step-by-step explanation:
From Analytical Geometry we know that the tangent line is a first order polynomial, whose form is defined by:
(1)
Where:
- Independent variable, dimensionless.
- Dependent variable, dimensionless.
- Slope, dimensionless.
- Intercept, dimensionless.
The slope of the tangent line at is:
(2)
If we know that ,
and
, then the intercept of the equation of the line is:
The equation of the line tangent to the graph of f at x = -1 is .
