Question 767699: Dear Sir/Madam,
Kindly help me in finding the value of k so that the equation 2x^2+(4-k)x-17=0, roots numerically equal but opposite in sign.
Thank you for your help!

for this to be true, (4-k) = 0
therefore k = 4, leaving an equation of
2x^2 - 17 = 0
2x^2 = 17
x^2 = 17/2
x = +/-
x
