IWhat is the value of the discriminant of the quadratic equation -2x2=-8x+8, and what does its value mean about the number of real number solutions the equation has?

Step-by-step explanation:

Given quadratic equation is

Multiplying by "-" on both sides

Now comparing the above quadratic equation in the  standard form of quadratic equation we get.

The values of , a = 2,  b=  -8, and c = 8

By Discriminant formula:

Substituting the values in the formula

We know that if the discriminant  D= 0, it has double real roots.

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,
