Answer:
Step-by-step explanation:
Given the expression , we are to re-write the expression in form of a partial fraction.
Before we write in form of a partial fraction, we need to note the expression at the denominator. <u>Since the expression in parenthesis is a quadratic equation, the equivalent numerator must be a linear expression.</u>
<u />
<u>Also the quadratic equation is a repeated form since it is squared</u>. This means that we are to repeat the quadratic equation twice when writing as a partial fraction.
From the above partial fraction, <em>it can be seen that x² + 7 in parenthesis was repeated twice and their equivalent expressions at the numerator are both linear i.e Bx+E and Dx+ E where A, B, C, D and E are the unknown constant.</em>
