Use the quadratic formula to solve for x.

ivann1987 [24]

Answer:

x = 1/3 + sqrt(5/2)/3 or x = 1/3 - sqrt(5/2)/3

Step-by-step explanation:

Solve for x:

6 x^2 - 4 x = 1

Divide both sides by 6:

x^2 - (2 x)/3 = 1/6

Add 1/9 to both sides:

x^2 - (2 x)/3 + 1/9 = 5/18

Write the left hand side as a square:

(x - 1/3)^2 = 5/18

Take the square root of both sides:

x - 1/3 = sqrt(5/2)/3 or x - 1/3 = -sqrt(5/2)/3

Add 1/3 to both sides:

x = 1/3 + sqrt(5/2)/3 or x - 1/3 = -sqrt(5/2)/3

Add 1/3 to both sides:

Answer: x = 1/3 + sqrt(5/2)/3 or x = 1/3 - sqrt(5/2)/3

7w + 6 + 2w = (w + 2)

Sindrei [870]

Hey there!

The correct answer is $w = \frac{-1}{2}$

$7w + 6 + 2w = w + 2$ ~ Write the equation

$9w + 6 = w + 2$ ~ Simplify

$8w + 6 = 2$ ~ Subtract $w$ from both sides

$8w = -4$ ~ Subtract $6$ from both sides

$w = \frac{-1}{2}$ ~ Divide both sides by 8

Hope it helps and have a great day!
