of real number solutions the equation has?

Answer 1

its options B)

Explanation:

 hope this helps

Answer 2

For this case we have the following quadratic equation:

`-2x ^ 2 = -8x + 8`

This is equivalent to:

`2x ^ 2-8x + 8 = 0`

Where:

`a = 2\\b = -8\\c = 8`

The discriminant is given by:

`d = b ^ 2-4 (a) (c)`

Substituting the values we have:

`d = (- 8) ^ 2-4 (2) (8)\\d = 64-64\\d = 0`

The discriminant is zero, so the equation has two equal real roots.

Answer:

The equation has two equal real roots.
