Given y = 2x2 - 10x. find all real values of x for which y = -3.

 The required values of x are

Step-by-step explanation:  We are given the following function of x :

We are to find all real values of x such that y = -3.

To find the required values of x, we must substitute y = -3 in equation (i).

Therefore, from equation (i), we have

We notice that both the values of x are real numbers.

Thus, the required values of x are

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6
