Question

if 3 is the zero of 2x^2-6k infind the value of k

Answer 1

Answer:

6

Step-by-step explanation:

2(3)^2-6k

6^2=6k

36=6k

k=6

Answer 2

Answer:

$2 {x }^{2} - 6k = 0$

Putting the value x = 3 in equation

$2 \times {3}^{2} - 6k = 0$

$18 - 6k \: = 0$

$6k = 18$

$k = 18 \div 6$

$k = 3$
