The 3 goes with the square root you don’t need to multiply or anything like that. If you need to simply for example 3 square root of 20 which is when 3 is outside the square root sign. The 20 will be separated with 4*5 in the square root and then you will square root the 4 leaving the 5 in and bringing 2 out. Now you can’t just bring it out and forget about the 3 outside you need to multiply that 2 and 3 and you get 6! So you final answer is 6 square root 5. Hope this helps reply if you have a question!
sorry but i don't know english friend if i knew i would tell you this time i failed
Answer:
be cautious of the answer
Step-by-step explanation:
Answer:
It can be written as 2(x-3)(x-3) or 2(x-3)².
Step-by-step explanation:
2x² - 12x + 18 = 2(x² - 6x +9) = 2(x-3)(x-3) =2(x-3)²
Step 1: Line up the equations so that the variables are lined up vertically.
Step 2: Choose the easiest variable to eliminate and multiply both equations by different numbers so that the coefficients of that variable are the same.
Step 3: Subtract the two equations.
Step 4: Solve the one variable system.
Step 5: Put that value back into either equation to find the other equation.
Step 6: Reread the question and plug your answers back in to check.
