Solve 6x2 = 12x − 24. a) the quantity of negative 2 plus or minus 3i square root 2 all over 2 b) 1 plus or minus i square root 3 c) the quantity of 2 plus or minus 3i square root 2 all over 2 d) 1 plus or minus 2i square root 10

Option B (±)

Step-by-step explanation:

1. To solve this problem you must use the Quadratic formula, which is used to solve quadratic equation. This formula is shown below:

2. Make the equation equal to zero. So, you must rewrite it as following:

3. Now, you must substitute values. Then, you have:

4. Then,you obtain the following result:

±

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
