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:
20
Step-by-step explanation:
If the ratio of boys is 9 there are 90 boys. If 9=90 then 1= 10. 10 x 2 = 20

Answer:
5² = 25
Step-by-step explanation:
log5 25 = 2
log(b) (x) = (y)
make b^(y) = (x)
5² = 25
I hope this helps!
x=0
because you must
determine the undefined range
write all numerators above the common denomonator
multiply the parenthesis
collect the alike terms
remove parenthesis
eliminate the opposites collect the like terms
set the numerator equal to 0
divide both sides by 6
check if thesolution is the defined range
if so then you would find your answer X=0
