Question

(3) With the help of the flow chart given below solve the equation x2 + 2√3x + 3 = 0using the formula.

Answer 1

On comparing it with ax2+bx+c,we get

a= 1,b=2√3,c=3

By using the formula,

x= -b +-√b^2+4ac/2a

-2√3+-√(2√3)^2+4×1×3/2×1

-2√3+-√12+12/2

-2√3+-√24/2

-2√3+-2√6/2

-2√3+-√6

The roots of the eqn. is -2√3+√6 and -2√3-√6
