Writing standard equation of a circle | Mathematics II | High School Math | Khan Academy

[@chroniclesofyash]

thank you so much, was so worried for my further maths GCSE!!!! This is so simple and makes perfect sense. Keep it up

[@akadush865]

pls help me in my homework.. the question is: Reduce the equation of the circle to the general form. given: x+2(y-x^2)=4+2y^2 what do i do first to make it into a general form? thanks in advance!

[@jazthesloth6635]

bro never got the answer

[@beamidrive]

thanks

[@SwiftyRay478]

Shouldn't it be equal to 74^2

[@leonoraschneider5188]

It's equal to r squared. Since r = (square root of 74), then r ^2 is (square root of 74) ^2 which is just 74.
