I want full solution.​

Answer 1

Step-by-step explanation:

Kx2 + 2x -1 = 0

One root of the equation is the opposite of the other root What is the value of K?

answer- 2

Answer 2

Answer:

For x^2 - Kx + 8 = 0: you ought to element the expression. Use a and b for the two numbers in the climate: (x - a)(x - b) = 0 For a to be two times b, a must be 2 and b must be 4: (x - 2)(x - 4) = 0 The roots are 2 and four. Multiplying those factors out provides a ok value of 6. For 25x^2 - 20x + m = 0: For the two roots to be equivalent, the left component ought to element to: (5x - a)^2 = 0 For that to artwork, a must be equivalent to 2 to get the 20m term. (5x - 2)^2 = 0 Multiplying that out, m equals 4
