Q. Multiply.\newlinex2+4x+3x1x+24x+12 \frac{x^{2}+4 x+3}{x-1} \cdot \frac{x+2}{4 x+12} \newlineSimplify your answer as much as possible.
  1. Identify Expressions: Identify the expressions to be multiplied.\newlineWe have two fractions to multiply: (x2+4x+3)/(x1)(x^2 + 4x + 3)/(x - 1) and (x+2)/(4x+12)(x + 2)/(4x + 12).
  2. Factor Numerators and Denominators: Factor the numerators and denominators where possible.\newlineThe numerator x2+4x+3x^2 + 4x + 3 can be factored into (x+1)(x+3)(x + 1)(x + 3).\newlineThe denominator 4x+124x + 12 can be factored into 4(x+3)4(x + 3).
  3. Rewrite with Factored Terms: Rewrite the original expression with the factored terms.\newlineThe expression becomes (x+1)(x+3)x1×x+24(x+3)\frac{(x + 1)(x + 3)}{x - 1} \times \frac{x + 2}{4(x + 3)}.
  4. Cancel Common Factors: Cancel out common factors from the numerator and denominator.\newlineThe (x+3)(x + 3) term is present in both a numerator and a denominator, so it can be canceled out.\newlineThe expression simplifies to (x+1)(x1)×(x+2)4\frac{(x + 1)}{(x - 1)} \times \frac{(x + 2)}{4}.
  5. Multiply Numerators and Denominators: Multiply the remaining numerators and denominators.\newlineMultiply the numerators: (x+1)×(x+2)(x + 1) \times (x + 2).\newlineMultiply the denominators: (x1)×4(x - 1) \times 4.
  6. Perform Numerator Multiplication: Perform the multiplication in the numerators.\newline(x+1)×(x+2)(x + 1) \times (x + 2) equals x2+2x+x+2x^2 + 2x + x + 2, which simplifies to x2+3x+2x^2 + 3x + 2.
  7. Perform Denominator Multiplication: Perform the multiplication in the denominators. (x1)×4(x - 1) \times 4 equals 4x44x - 4.
  8. Write Final Expression: Write the final simplified expression.\newlineThe final simplified expression is (x2+3x+2)/(4x4)(x^2 + 3x + 2)/(4x - 4).
