Hey there!

The formula for the discriminant is represented by b²-4ac.
We need to identify the values for a, b, and c.
This equation is in general form, which is ax² + bx + c = 0.
So, a = -2, b = -1, and c = -1.
Plug the values into the formula.
(-1)²-4(-2)(-1)
Square.
1-4(-2)(-1)
Multiply.
1-4(2)
1-8
Subtract.
-7
The discriminant is -7.
This means there are no real solutions to the equation, because the discriminant is negative.
Hope this helps!
<u>Distinguish between an Ice Age from an interglacial:</u>
Ice age is the period of time when the glacial advancement takes place at such a level that all the water bodies turn into ice and the interglacial is the period of time between the ice ages where the glacier melts and the sea level rises.
So also, an interglacial or interglacial period is the hotter timeframe between ice ages where icy masses retreat and ocean levels rise. The glacier retreats and it becomes warm. Whereas during ice age the sea level falls down and glaciers are formed. These are the major differences between Ice age and interglacial period.
