Question

If the equation ax² square + bx + c = 20 is not altered when each of the coefficient is increased by the same quantity then X square + X + 1=

Answer 1

i want to know that how you put the power of 2 in x 

Answer 2

The roots of the quadratic equation ax2 + bx + c = 0, where a, b, & c are real numbers,
and a ? 0, are given by the following formula:
 
In this formula the term b2-4ac is called the discriminant. If b2 - 4ac = 0, so the
equation has a single repeated root. If b2 - 4ac > 0, the equation has two real roots.
If b2-4ac < 0, the equation has two complex roots. Write a program that reads the
following three sets of values for a, b & c [{1, 3, 1}, {1, 2, 1}, {2, 1, 1}]. The
program should use a function other than the main function. The function must be
named DetermineRootTypes(). This function should be invoked from the main()
function and should be passed the values of the parameter (a, b, and c). The main
task of this function is to compute the discriminant for the given parameter values
and return to the calling function an integer number that can have one of three
values (1 if the roots are real, 2 in case of repeated roots, and 3 in case of
imaginary roots). The calling function, main(), is in charge of repeating the
following four activities three times using a loop: receiving the parameter values
from the keyboard (three values for a, b and c in every loop iteration), calling the
function DetermineRootTypes(), computing the roots in case of real and repeated
roots, then finally output the actual root values (if any).
