Answer:
2 and -3
Step-by-step explanation:
2x^2=4x
4x+2x=12
6x=12
how many times does 6 go into 12?
right, 2 times!
x=2
---
2x^2+2x-12=0
x^2+x-6=0
(x+3)(x-2)=0
X=-3 and 2
PH is calculated by the negative logarithm of the hydrogen concentration in a solution. Therefore, the pH in this case is:
pH = -log (0.0000006)
