Question

kx2+2x-4=0 x=-1/2 find the value of k.​

Answer 1

Step-by-step explanation:

$kx { }^{2} + 2x - 4 = 0$

$x = \frac{1}{2}$

keep the value of x in equation

$k \times (\frac{1}{2} ) {}^{2} + 2 \times \frac{1}{2} - 4$

$\frac{k}{4} + 1 - 4 = 0$

$\frac{k}{4} - 3 = 0$

$\frac{k}{4} = 3$

K= 12. answer
