Q. Multiply.x−1x2+4x+3⋅4x+12x+2Simplify your answer as much as possible.
Identify Expressions: Identify the expressions to be multiplied.We have two fractions to multiply: (x2+4x+3)/(x−1) and (x+2)/(4x+12).
Factor Numerators and Denominators: Factor the numerators and denominators where possible.The numerator x2+4x+3 can be factored into (x+1)(x+3).The denominator 4x+12 can be factored into 4(x+3).
Rewrite with Factored Terms: Rewrite the original expression with the factored terms.The expression becomes x−1(x+1)(x+3)×4(x+3)x+2.
Cancel Common Factors: Cancel out common factors from the numerator and denominator.The (x+3) term is present in both a numerator and a denominator, so it can be canceled out.The expression simplifies to (x−1)(x+1)×4(x+2).
Multiply Numerators and Denominators: Multiply the remaining numerators and denominators.Multiply the numerators: (x+1)×(x+2).Multiply the denominators: (x−1)×4.
Perform Numerator Multiplication: Perform the multiplication in the numerators.(x+1)×(x+2) equals x2+2x+x+2, which simplifies to x2+3x+2.
Perform Denominator Multiplication: Perform the multiplication in the denominators. (x−1)×4 equals 4x−4.
Write Final Expression: Write the final simplified expression.The final simplified expression is (x2+3x+2)/(4x−4).
