In an algebra problem, you don't set the answer-goal and say "Go for it!"
There is only one correct answer, so the only appropriate way to go about it is to say "Here is the equation. Find the solution.?"
Maybe 27 is the solution, and maybe it's not.
We're about to find out.
You said 2/3 x - 7 = 11
Add 7 to each side: 2/3 x = 18
Divide each side by 2 : 1/3 x = 9
Multiply each side by 3 : x = 27 .
So yes, the correct solution is 27. And that's how to find it.
Answer:
Step-by-step explanation:
The given quadratic expression is
3x² - 9x + 6
Dividing each term in the expression by 3 in order to simplify it further, it becomes
x² - 3x + 2 = 0
We would determine two numbers such that their sum or difference is -3x and their product is 2x².
The two numbers are - 2x and - x.
Therefore,
x² - 2x - x + 2
x(x - 2) - 1(x - 2)
(x - 1)(x - 2)
When the expression is factored completely, it is equivalent to
(x - 1)(x - 2)
