1. Synthetic division by $\left( {ax - b} \right)$
Operate synthetic division and write the division statement.
1. $\left( {8{x^3} - 14{x^2} + 7x - 1} \right) \div \left( {2x - 5} \right)$
2. $\left( {29{x^3} - 12{x^4} - x} \right)$ $\div$ $\left( {5 - 3x} \right)$
###### Topic Notes
Synthetic division is a shortcut method of dividing polynomials as opposed to long division. Yet, this method can only be used when we are dividing a liner expression and the leading coefficient is a 1.
