To find the roots of a quadratic equation you need to use the quadratic formula
This implies that if the equation has no solutions, if the equation has one double solution, and two distinct solutions otherwise.
So, the pseudocode could be something like this:
double delta = b*b - 4*a*c;
if (delta < 0) print ("There are no real solutions!");
else if(delta = 0) {
double x = -b/(2*a);
print("There is a double solution: " + x);
} else {
double det = sqrt(delta);
double x1 = (-b+det)/(2*a);
double x1 = (-b-det)/(2*a);
print ("The two solutions are " + x1 + "and" + x2);
}
A because -2 -3 -4 ext are less than -1
Answer:
B. 20/72 sq ft
Step-by-step explanation:
5/8(4/9) = 20/72 ft² = 5/18 ft²
Answer:
Sampling bias. Remedy is to use Systematic Random Sampling techniques
Step-by-step explanation:
It is a sampling bias because it denies the other party the opportunity to respond to same question to determine their opinions
The possible remedy to this study is to adopt the systematic random sampling approach to make provision for other party to also respond to same question before an inference or conclusion is reached.
