Exercise
$\frac{x-1}{4x+4}-\frac{x+b}{8x-8}$
Step-by-step Solution
Learn how to solve problems step by step online. Simplify (x-1)/(4x+4)+(-(x+b))/(8x-8). Simplify the product -(x+b). Factor the polynomial 4x+4 by it's greatest common factor (GCF): 4. Factor the polynomial 8x-8 by it's greatest common factor (GCF): 8. The least common multiple (LCM) of a sum of algebraic fractions consists of the product of the common factors with the greatest exponent, and the uncommon factors.
Simplify (x-1)/(4x+4)+(-(x+b))/(8x-8)
Final answer to the exercise
$\frac{x^2-5x+2-xb-b}{8\left(x^2-1\right)}$
