3(2X^2 + 6X +3) = 6X^2 + 18X + 9
 
 
This is the quadratic equation  aX^2 + bX + C
 
Where X is the unknown variable to be resolved, and  a,b,c are constants
 
Soluttion:
 
X 1,2
 
3(2X^2 + 6X +3) = 6X^2 + 18X + 9

This is the quadratic equation aX^2 + bX + C

Where X is the unknown variable to be resolved, and a,b,c are constants

Solutions:

X12 = ( - b +- √ (b^2 – 4ac) )/2a

Solution 1:

X1 = ( -18 + √ (18^2 – 4*6*9) )/2*6 = ( -18 + √ (324 – 216) )/12 = ( -18 + √ (108) )/12

X1 = -18/12 + √ (108)/12

Solution 2:

X2 = ( -18 - √ (18^2 – 4*6*9) )/2*6 = ( -18 - √ (324 – 216) )/12 = ( -18 - √ (108) )/12
X2 = -18/12 - √ (108)/12
