Section 1.5 : Factoring Polynomials
For problems 1 – 4 factor out the greatest common factor from each polynomial.
- \(6{x^7} + 3{x^4} - 9{x^3}\) Solution
- \({a^3}{b^8} - 7{a^{10}}{b^4} + 2{a^5}{b^2}\) Solution
- \(2x{\left( {{x^2} + 1} \right)^3} - 16{\left( {{x^2} + 1} \right)^5}\) Solution
- \({x^2}\left( {2 - 6x} \right) + 4x\left( {4 - 12x} \right)\) Solution
