Question

3. Determine k so that the given equation will have the stated property, and write the resulting equation:
(a) x
2 + 4kx + k + 2 = 0 has one root.
(b) 4x
2 − 8kx − 9 = 0 has one root the negative of the other.
(c) 4x
2 − 8kx + 9 = 0 has roots whose difference is 4.
(d) 2x
2 − 3kx + 5k = 0 has one root twice the other.
(e) 3x
2 + (k − 1)x − 2 = 0 equal and opposite

Answer 1

Answer:

2 + 4 K X + K + 2 equal 051 Bheem for multiple 2 - 8 ke multiple - 9 = 0 and 1 with nitrogen of the others see for multiple 2 - 8 x + 9 = 0 have a metaphor for the to multiple 2 - 3 x + 5 = 0 route to win the over (a multiple of 2 +) ke minus x minus 20 equal and opposite
