hey mate here is your answer
Answer:
A) Real Roots
B) Imaginary Roots
C) Equal Roots
D) Unequal Roots
E) Rational Roots
F) Irrational Roots
Step-by-step explanation:
The equation with one variable , in which the highest power of variable is two , is know as QUADRATIC EQUATION
ex - 3x² + 4x + 7 = 0
Every quadratic equation gives to values of unknown variables and these values is called roots of equation .
The quadratic equation have three roots :
A) Real Roots
B) Imaginary Roots
C) Equal Roots
D) Unequal Roots
E) Rational Roots
F) Irrational Roots
The nature of Roots depends entirely on the value of it Discriminant
If D = 0 , Roots are real and equal
If D
, roots are real and unequal
If D
,roots are imaginary
where D = b² - 4ac for any quadratic equation ax² + bx + c = 0
Answer
Answer:
6 students.
Step-by-step explanation:
let the number of students in class be<em> x</em>
Since Half of the class represents half of the students, therefore
Number of student who got A in test = 
Now if one more student got A in test then the number of students who got A in test will be 
Now according to equation,


Further solving


Hence the total number of students in class is 6.
(2,-4) is a solution to the equation.
