use PEMDAS

The numbers in the absolute value symbols are what you need to solve first:

I2-4(3-6)I

I2-4(-3)I simplify the parentheses

I2+12I multiply -4 and -3

I14I add the terms 2 and 12

14 simplify 14 with the absolute value symbols

Now solve what's on the outside of the absolute value symbols:

23-2

21 subtract and simplify 23 and -2

Finally, multiply the two terms we have made, 14 and 21:

14 * 21 = 294

Your final answer should be 294.

Convert x2 + y2 -4x = 0 to polar form.

Bingel [31]

Answer:

$r(r-4\cos \theta)=0$

Step-by-step explanation:

We are given the following equation:

$x^2 + y^2 -4x = 0$

We have to convert it into polar form.

We put

$x = r \cos \theta\\y = r\sin \theta$

Putting values, we get:

$x^2 + y^2 -4x = 0\\(r\cos \theta)^2 + (r\sin \theta)^2 - 4(r\cos \theta) = 0\\r^2(\cos^2 \theta + \sin^2 \theta) - 4r\cos \theta = 0\\r^2 - 4r\cos \theta = 0\\r(r-4\cos \theta)=0$

is the required polar form.
