Chapter 8, Problem 19PT

To determine

To factor the given polynomial

Answer to Problem 19PT

  $a(a-2)$

Explanation of Solution

Given:

Polynomial: $a^2-2a$

Calculation:

Consider the given polynomial,

  $\Rightarrow a^2-2a$

Find out common terms in the above expression.

  $\begin{array}{l}\Rightarrow a^2-2a\\ \Rightarrow a(a-2)\end{array}$

Therefore, the polynomial can be factorised as,

  $\Rightarrow a(a-2)$

Conclusion:

Therefore, the polynomial is factored as $a(a-2).$
