what is the value of the discriminant of the quadratic equation -2x^2 -8x+8 and what does it value mean about the number about the number

Answer:0Step-by-step explanation:It is been considered that Discriminant is calculated by the following formula:D = b*b - 4 * a * cIn order to simplify the calculations we can divide all the numbers by 2 and we will have the same quadratic equation:-x^2 -4x+4=0and as usual quadratic equation is presented as the following:ax^2 - bx + c = 0so in our case a = -1; b = -4; c = 4;Then D = -4*4 -4*(-1) * 4 = -16+16 = 0I am not quite understanding the following phrase:"and what does it value mean about the number about the number" but if the question was in regards of the following number '-2x^2' so number ^2 is actually the value of power so 'x' is multiplied on it is own and this equation basically means the following:-2x^2 = -2 * (x) * (x)
