Question

If one root of 2x² + x - 6 = 0 is 2, find the value of k and the other root.​

Answer 1

Answer:

other root is equal to minus 3/2

Answer 2

Answer:

There is no k in the question. But I can solve the quadratic equation for you

$2{x}^{2} + x - 6 = 0 \\ 2 {x}^{2} + 4x - 3x \: - 6 = 0 \\ 2x(x + 2) - 3(x + 2) = 0 \\ (2x - 3)(x + 2) = 0 \\x = 3/2 \: or \: x = - 2$
