What is the solution to the following equation? x^2+3x+4=0

a) x=1; x=-3
b) x=3; x=-1
c) x= -3+- square root of -7/ 2
d) x= 3+- square root of 25/2

x =−3±i√7/2

is the correc anwer

Option C

The solution of equation x^2+3x+4=0 is x= -3+- square root of -7/ 2

Solution:

Need to identify correct option for solution of the equation x^2 + 3x + 4 = 0.

Given equation is quadratic equation. We can find solution of this equation using quadratic formula.

According to quadratic formula for general equation solution of the equation is given by  

The given equation is So in our case, a = 1, b = 3 and c = 4

On applying quadratic formula we get

As i is square root of -1,

Hence correct option is C that is roots of quadratic equation

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
