Given the expression:
.

.
Evaluate the expression if a=-2 b=5, c=-4, and d = 6
.
All you need to do is to substitute the given values for a, b, c, and d into the given
expression and then simplify it.
.
Put -2 in place of a, +5 in place of b, -4 in place of c, and +6 in place of d and the given
expression becomes:
.

.
Multiply out the terms in the first two sets of parentheses to get:
.

.
In the third term divide -4 by -2 to get +2 and the expression then becomes:
.

.
Finally, 20 + 30 - 2 algebraically adds to 50 - 2 which is 48.
.
The answer to the given problem is 48.
.
Hope this helps you to see how to solve this problem by substituting numbers in place of
the letter variables.
