Expert Solution
Check Mark

Answer to Problem 35WE

For k=±2 there exists a real double root condition.

Explanation of Solution

Given information: The given quadratic equation is,

  kx24x+k=0.... (1)

Formula used: The discriminant (D=b24ac) of a quadratic equation ax2+bx+c=0 where (a0) should be equal to zero for the real double root condition.

Mathematically,

  b24ac=0.... (2)

Calculation: From (1), evaluate discriminant (D) and equate that to zero according to formula (2).

  D=(4)24(k)(k)....{a=k,b=4and c=k}0=164k2.... (D=0 for double root)or, k2=4k=±4k=±2

Answer to Problem 35WE

For 2<k<2 the equation has two different real roots

Explanation of Solution

Given information: The given quadratic equation is kx24x+k=0 .

Formula used: The discriminant (D=b24ac) of a quadratic equation ax2+bx+c=0 where (a0) should be greater than zero for two different real root condition.

Mathematically,

  b24ac>0.... (3)

Calculation: From (1), evaluate discriminant (D) and apply the formula (3).

  (4)24(k)(k)>0....{a=k,b=4and c=k}164k2>0or, k2<4(k2)(k+2)<02<k<2
