Q. The polynomial \newlinep(x)=5x344x2+61x+14p(x)=5x^{3}-44x^{2}+61x+14 has a known factor of \newline(x7)(x-7).\newlineRewrite \newlinep(x)p(x) as a product of linear factors.\newlinep(x)=p(x)=
  1. Perform Polynomial Division: Step 11: Perform polynomial division to divide p(x)p(x) by (x7)(x-7).\newlineCalculation: Using synthetic division with root 77,\newline5x344x2+61x+145x^3 - 44x^2 + 61x + 14 divided by x7x - 7:\newline\begin{array}{r|rrrr} 7 & 5 & -44 & 61 & 14 \ \hline & & 35 & -63 & -14 \ \hline & 5 & -9 & -2 & 0 \end{array}\newlineResult: 5x29x25x^2 - 9x - 2
  2. Factorize Quadratic Equation: Step 22: Factorize the quadratic equation 5x29x25x^2 - 9x - 2.\newlineCalculation: Using the AC method, where A=5A=5, B=9B=-9, C=2C=-2,\newlineProduct AC=10AC = -10, Sum B=9B = -9,\newlineFactors of 10-10 that add up to 9-9 are 10-10 and 11,\newlineRewrite middle term: A=5A=500,\newlineGroup: A=5A=511,\newlineFactor out common terms: A=5A=522,\newlineFactor by grouping: A=5A=533
  3. Write as Linear Factors: Step 33: Write p(x)p(x) as a product of linear factors.\newlineCalculation: p(x)=(x7)(5x+1)(x2)p(x) = (x - 7)(5x + 1)(x - 2)
