Intermediate Algebra
Simplify the expression 4x36x2\(\frac{4x^3}{6x^2}\).
Identify the numerator and denominator in the expression 3x2+1x−4\(\frac{3x^2+1}{x-4}\).
Evaluate x2−4x−2\(\frac{x^2-4}{x-2}\) at x=3x = 3, and confirm the value is allowed by the domain.
Simplify x2−5x+6x2−4⋅x+2x−3\(\frac{x^2-5x+6}{x^2-4}\[\cdot\]\frac{x+2}{x-3}\) and state any excluded xx-values.
If a rational expression has a common factor (x + 1) that cancels in simplification, must x = -1 be excluded from the simplified expression's domain?
