Question

If m<1 = (2x)° and m<5 = (x+16)°, find the value

of ‘x’ and the m<4.

Answer 1

Given equation is

<br> Comparing with

, we get a=1, b=2(m-1), c=m+5 <br> The equation will have two real and equal roots if <br> Discriminant (D)=0 <br>

<br> or

<br>

<br>

<br>

<br>

<br>

<br>

<br>

<br>

Hence, value (s) of m are -1 and 4.
