For a quadratic equation ax^2 + bx + c = 0, the discriminant is given by b^2 - 4ac
Thus for a^2 - 2a + 5 = 0,
a = 1, b = -2 and c = 5
b^2 - 4ac = (-2)^2 - 4(1)(5) = 4 - 20 = -16
A (-9.5, -9.5) B (5.5,-2.5) C (3.5,3.5)
It is a rhombus
It is so because all its sides are equalto 10cm.
opposite angles are equal. in a parallelogram opposite angles are equal but all sides aren't equal but in case of a rhombus it is so.

256.
The coefficient of just the y term would be 256 because the entire expanded equation looks like this:
y^4+16y^3+96y^2+256y+256
The price of the turkey based on the percentage given is $15.81.
<h3>How to illustrate the information?</h3>
It was stated that the cost is $15.50 but that there was a 2% increment in price.
Therefore, the new price will be:
= $15.50 + (2% × $15.50)
= $15.50 + $0.31
= $15.81
