Assume the expression is:
4/(x + 2) + 6/(x + 5)
Simplify this expression by combining the expressions altogether. Let's go step by step.
Step 1: Determine the LCD of the expression.
The LCD of the expression is (x + 2)(x + 5). Multiply the top and bottom of each fractional expression by whatever factor the denominator is missing!
4/(x + 2) * (x + 5)/(x + 5) + 6/(x + 5) * (x + 2)/(x + 2)
Step 2: Combine the expression and simplify.
(4(x + 5) + 6(x + 2))/((x + 2)(x + 5))
= (4x + 20 + 6x + 12)/((x + 2)(x + 5))
= (10x + 32)/((x + 2)(x + 5))
