Question

If x=-1/2 is a solution of the quadratic equation 3x square +2kx-3=0,find the value of k.

Answer 1

HELLO DEAR,

given that:-

X= -1/2

put this value in the Equation,

3X² + 2kX -3 =0

$3( { - \frac{ 1}{2} })^{2} + 2k (- \frac{ 1}{2} ) - 3 = 0 \\ = > 3 \times \frac{1}{4} - 2k \times \frac{1}{2} - 3 = 0 \\ = > \frac{3}{4 } - k - 3 = 0 \\ = > 3 - 4k - 12 = 0 \\ = > 4k = - 9 \\ = > k = - \frac{9}{4}$
