Algebra Math:

This is my  video Math tutorials in you-tube channel.

Quadratic Equation  

Quadratic Equation:
The standard form of quadratic equation is ax2+bx+c=o
 Solve:  3x2+5x+2=0
 Here,
     3x2+5x+2=0
=> 3x2+3x+2x+2=0
=> 3x(x+1)+2(x+1)=0
=> (x+1)(3x+2)=0

Either
    x+1=0
=> x=-1
OR
    3x+2 = 0
=> 3x = -2
=> x = -2/3
The required values of x are
x=-1  and  x=-2/3     Ans.
