Solve the equation using the quadratic formula 3x^2 = 2 (2x+1)

Step 1: Make equation equal to Zero

3x^2 = 4x + 2

3x^2 - 4x - 2

Step 2: use equation

a = 3 b = - 4 c = - 2

after plugging in answer should be

(2 + or - sqrt 10) / 3

3x² = 2 (2x+1)

Expand the brackets

3x² = 4x + 2

Rearrange

3x² - 4x - 2 = 0

Quadratic formula is

(-b ± √ (b² - 4ac)) / 2a

Where

a = 3

b = - 4

c = - 2

Therefore, putting these values in to the quadratic formula:

x = 15.487

or

x = - 3.487

Round the answers how you will.
