1 answer:
Answer:
This question is incomplete, it should read 3x² - 10x + 8. The answer is (3x-4) (x-2).
Please find the solved explanation to this question attached
Explanation:
To factorize means to write an expression as a product of its factors using brackets. It is the opposite of expanding an algebraic expression i.e. it involves contracting it using factors common to the variables.
In this question, 3x² - 10x + 8 is given
For the sum, which is -10x, and product, which is 24x², -6x and -4x are the two variables whose sum will give rise to -10x and also whose product will give rise to 24x².
We have;
3x² - 10x + 8
3x² - 6x - 4x + 8
Next, we look for factors of each pair of expression.
3x (x - 2) - 4 (x - 2)
(3x - 4) (x - 2)

Hello!
In this case, since a dilution process implies that the moles of the solute remain the same before and after the addition of diluting water, we can write:
Thus, since we know the volume and concentration of the initial sample, we compute the resulting concentration as shown below:
