Simplify 6x2−12x3x\(\frac{6x^2-12x}{3x}\) to the lowest terms.
Which factorization is the first step to simplify 2x2+6x4x\(\frac{2x^2+6x}{4x}\)?
Add the rational expressions: 2x+1+3x−2\(\frac{2}{x+1}\)+\(\frac{3}{x-2}\)
Combine and fully simplify: 2xx2−9+3x+3\(\frac{2x}{x^2-9}\)+\(\frac{3}{x+3}\)
You must add 4x2−5x+6+12x\(\frac{4}{x^2-5x+6}\)+\(\frac{1}{2x}\). A student uses the LCD 2x(x−2)(x−3)2x(x-2)(x-3). Provide the best justification statement for why this LCD is appropriate.
