Answer:

1127

Step-by-step explanation:

Using PEMDAS rules, we first add anything in parentheses:

(59 + 56) x 10 - 23 becomes (115) x 10 - 23

Then we do exponents, which we don't have so we skip it

Then we do either multiplication or division (whichever one comes first)

115 x 10 - 23 becomes 1150 - 23

Then we do either addition or subtraction (whichever one comes first)

1150 - 23 becomes 1127

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
