Given:
The given quadratic equation is:
To find:
The solution for the given quadratic equation in simplest form by using the quadratic formula.
Solution:
Consider a quadratic equation is defined as 
, then the quadratic formula is:
The given quadratic equation is:
We have, 
. Using the quadratic formula, we get
![[\because \sqrt{-a}=i\sqrt{a}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csqrt%7B-a%7D%3Di%5Csqrt%7Ba%7D%5D)
The solutions of the given equations are 
and 
.
Hence, the correct option is B.
D -2, 4 is in the second quadrant because the -x brings it to the left side and the positive 4 puts it in the upper of the left side which is the second quadrant
Answer:
Step-by-step explanation:
The answer is B
The whole numbers are the + integer set. Since -sqrt(25) = - 5, this number is not included in the whole number set.
-10.6, and 9/10, are the constants
Answer:
Step-by-step explanation:
Given is a non homogeneous second degree equation as
Auxialary equation is
Hence general solution is
x = Acos 2t + B sin 2t
Particular integral is = 
Since t has coefficient 1, we substitute
Hence full solution is
