Answer:
If D< 0, the roots of the quadratic equation will b complex.
Step-by-step explanation:
Let 
is the given quadratic equation.
So, if the Discriminant (D) = 
, the the equation will have only complex solutions.
Complex roots are represented in the form of 
1. <u> x represents the X axis (real) co ordinate,</u>
<u>y represents the Y axis (imaginary) coordinate</u>
<u />
<u />
2. Also, the graph of the with equation D < 0 NEVER CROSSES the X - axis, as there are no real roots of the equation, only complex roots.
3. Here. roots are always identical but are opposite in signs. Such pair or roots with opposite sign are called CONJUGATE PAIRS.

Answer:
40%
Step-by-step explanation:
<h3>so have 5 rectangles in a whole.</h3><h3>we also have 2 shaded potions in that whole which represents 2/5 shaded potions.</h3>
<h3>2/5 in fraction =0.4</h3>
<h3>Now Change 0.4 to percentage by multiplying 0.4 by 100</h3>
<h3>0.4 x 100 = 40</h3><h3>Therefore the percentage represented by the shaded area is 40%</h3><h3> </h3><h3>Hope this helps.</h3><h3>Good luck ✅.</h3>
Dilation by a scale factor of 1/2 followed by a translation of 1.5 units down.
<h3>What is dilation?</h3>
Dilation is a transformation, which is used to resize the object. Dilation is used to make the objects larger or smaller.
Here, △ HIJ are:
IH = 3
IJ = 4
then using the scale factor = 1/2 we get
Therefore, we have:
I'H '= 1.5
I'J '= 2
Hence, dilation by a scale factor of 1/2 followed by a translation of 1.5 units down.
