Answer :

Answer:

x = ⅔ Or x = 2

Explanation:

3x² − 8x + 4 = 0

Factor left side of equation

(3x − 2)(x − 2) = 0

Set factors equal to 0

3x − 2 = 0 or x − 2 = 0

x = ⅔ or x = 2

Quadratic equations are a form of algebraic equations that can or cannot be factorized.

The value of x is 2  and 2/3

Quadratic equations come in the form: ax²+ bx + c = 0

Solution by completing the square for:

3x²− 8x + 4 = 0

a = 3 , a≠1 so  we divide through by 3

3x²/3 − 8x/3 +4/3 = 0/3

which gives us

x²− 8x/3 + 4/3 = 0

Subtract 4/3 from both sides

x²− 8x/3 + 4/3 - 4/3  = 0 - 4/3

 x² − 8x/3 = −4/3

Take half of the x term and square it  and  add the result to both sides

x² − 8x/3 + 16/9 = −4/3 + 16/9

Rewrite the perfect square on the left

(x − 4/3)² = −4/3 + 16/9

and combine terms on the right

(x − 4/3)²= 4/9

Take the square root of both sides

x − 4/3 = ±√4/9

Simplify  

x − 4/3 = ±2/3

Collect like terms

x = 4/3 ± 2/3

  • Solving for x

x = 4/3 + 2/3

x = 6/3

x = 2

Also:

x=4/3 − 2/3

which becomes

x = 2/3
