please and thanks :)

Step-by-step explanation:

128-32=96

96/16=6

You must do order of operations (PEMDAS) in order to solve this problem.

So, first start with the exponents. 8^2 is the same as 8 × 8 which is 64, and 2^2 is the same as 2 × 2 which is 4. So now you have 2 × 64 - 4 × 8 over 2 × 8.

Next multiply 2 and 64 to get 128, and multiply 4 and 8 to get 32. Now subtract 32 from 128 to get 96. Next multiply 2 and 8 to get 16. So you should be left with 96/16, which also means 96 ÷ 16, which equals 6.

So your answer is 96/16 or 6 to be exact. I hope you like this answer, and good luck, friend :)

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

the answer is 489
