a,0;two imaginary solution
b,0;0ne real solution
c,c,200;two real solution
d,0;two real solution

Answer 2

Write the quadratic equation in standard form
Divide both sides by -5
k^2-2k+13/5=8/5
Solve the quadratic equation by completing the square
Then subtract 13/5 from both sides
k^2-2k=-1
take one half of the coefficient of k and square it, then add it to both sides
Add 1 to both sides
k^2-2k+1=0
Factor the left side
Write the left side as a square
(k-1)^2=0
Eliminate the exponent on the left side
Take the square root of both sides
k-1=0
solve for k
add 1 to both sides
k=1
