The complex solution of a quadratic equation are (- 2 + i ) and
(- 2 - i ).
What is Quadratic equation?
An algebraic equation of the second degree is called a quadratic equation.
Given that;
A quadratic equation is;
3x² = -12x - 15
Now, The equation is written as;
3x² + 12x + 15 = 0
Take 3 common, we get;
3 (x² + 4x + 5) = 0
x² + 4x + 5 = 0
Factorize the equation by using Sridharacharya Formula;
x = - 4 ± √4² - 4*1*5 / 2*1
x = -4 ± √16 - 20 / 2
x = - 4 ± √-4 / 2
Since, √-1 = i
x = -4 ± 2i / 2
x = - 2 ± i
It gives two values of x as;
x = - 2 + i
And, x = - 2 - i
Hence, The complex solution of a quadratic equation are (- 2 + i ) and
(- 2 - i ).

Answer:
a) Phenomenological method
Step-by-step explanation:
Definitions of all the options are as follows:
Phenomenological: Phenomenology is the study of structures of consciousness as experienced from the first-person point of view.
Ethnography : The scientific description of peoples and cultures with their customs, habits, and mutual differences.
Experimental : Relating to an experiment that is good to describe things that was in trail stage or it involves a hypothesis being tested through the experiment
ex post facto : Ex post facto is a Latin phrase that essentially means "retroactive," or affecting something that's already happened. This research design is a method in which groups with qualities that already exist are compared on some dependent variable
<u><em>The correct answer is Phenomenological method as the researcher was interested in the person's conscious experience which means the method of choice would be phenomenological as described by the definition above it is study of structures of consciousness experienced.</em></u>
Answer:
The transformation in this figure is rotation.
Step-by-step explanation:
The transformation in this figure is rotation.
There are four types of transformation.
<u>Translation:</u>
Movement of the object without rotating it or changing its size.
<u>Reflection:</u>
Flipping the object about a line of reflection. The mirror image is formed after transformation.
<u>Dilation:</u>
Changing the size of a figure without changing its essential shape.
<u>Rotation:</u>
A rotation is a transformation that turns a figure about a fixed point called the center of rotation.An object and its rotation are the same shape and size, but the figures may be turned in different directions....
Answer:
Proportion of chocolate in biscuit tin = 5:7
Step-by-step explanation:
Given:
Number of chocolate in biscuit tin = 10
Number of shortbread biscuits in biscuit tin = 4
Find:
Proportion of chocolate in biscuit tin
Computation:
Proportion of chocolate in biscuit tin = Number of chocolate in biscuit tin / Total product in biscuit tin
Proportion of chocolate in biscuit tin = 10 / [10 + 4]
Proportion of chocolate in biscuit tin = 10 / 14
Proportion of chocolate in biscuit tin = 5:7
