Answer:
x = (4 + 2√34)/10, x = (4 - 2√34)/10
Step-by-step explanation:
5x² - 4x = 6
Subtract: 5x² - 4x - 6 = 0
Quadratic formula: x = (4 ± √(16 - 4*5*(-6)))/10
Multiply: x = (4 ± √(16 + 120))/10
Simplify: x = (4 ± 2√34)/10
Answer:

Step-by-step explanation:

First you need to make the 12 5/8 into an improper fraction by multiplying 12 by 8 and then adding the total by 5.
-> 
Now you have
so you need a common denominator by multiplying the first fraction by 2

Then you subtract 160 - 101 which equals 59.
