Answer:
-5cd
Step-by-step explanation:
<u>Simplifying:</u>
- -3cd - d(2c - 4) - 4d = ⇒ parenthesis
- -3cd - 2cd + 4d - 4d = ⇒ simplify like terms
- -5cd ⇒ answer

Answer:


Step-by-step explanation:
first, subtract the two fractions
You will have
the un-simplified difference of those expressions
Lets try to simplify that
Lets find the roots of the polynomial from the bottom using the formula for quadratic equation, (-b +/- sqrt( b2-4*a*c)) /(2*a)
Which are x=-3, and x=1
Thus, you have (x+3)*(x-1)
So
