    <div class="ateTopicHead" style="margin:0px; padding:0px; width:853px; text-align:start; -webkit-text-stroke-width:0px">

     

    Find the value of 'a' if (x - a) is a factor of x5 - a2x3 + 2x + a + 3. Hence, factorise x2 - 2ax - 3.

    </div> <div class="qsnDetails" style="margin:0px; padding:0px; text-align:start; -webkit-text-stroke-width:0px">

    <font color="#000000">A N S W E R</font>

    </div> <div class="expertBlock" style="margin:0px; padding:0px; text-align:start; -webkit-text-stroke-width:0px">

     

    Let p(x) = x5-a2x3+2x+a+3

    Since, (x-a) is a factor of p(x), so p(a) = 0

     

    </div>
