What is x if 2y+x^2=5y+1? ____ x = ±√3y+1 Where the range of y is: y ≥ -1/3

an+bn=cn << does a such combination of INTEGERS exists with n>2 ? ( ͡° ͜ʖ ͡°)

a n+b n=c n << does a such combination of INTEGERS exists with n>2 ? ( ͡° ͜ʖ ͡°) Auming that: a ≥ 1, b ≥ 1, c ≥ 1 Let n be 3 first... Let a k be a sequence of numbers where a k = k 3Finding the difference of each term, you should get a k+1-a k = (k-1) 3-k 3 = 3k 2+3k+1 Now find a cube that equals to 3k 2+3k+1. The only solution that can be found is But that solution isn't even an integer. Therefore, there is no such combination when a ≥ 1, b ≥ 1, c ≥ 1

x²+y²+9x+2y=0 << I want A(x0,y0) and r²
I hope you know what does this equation means, or I kill you

x²+y²+9x+2y=0 << I want A(x 0,y 0) and r² I hope you know what does this equation means, or I kill you This is an equation of a circle. The standard equation of a circle is (x-x 0) 2+(y-y 0) 2=r 2Rearranging the equation to make it that way.. (x+9/2) 2+(y+1) 2 = 85/4 __ The center of the circle is (-9/2,-1), and the radius of the circle is √85/2

nice!
what is the method to develop any (a+b)n form for any "n" without wasting time with all the "(a+b)(a+b)..." ?

spot the error:
i^2=1/-1 i^2=1/(i^2) i=1/i ii=i/i i^2=1 -1=1
( ͡° ͜ʖ ͡°)

spot the error: i^2=1/-1 i^2=1/(i^2) i=1/i ii=i/i i^2=1 -1=1 ( ͡° ͜ʖ ͡°) The third step. ( ͡° ͜ʖ ͡°) You divided i on the left side and multiplied i on the right side. Which makes it not equal anymore. ( ͡° ͜ʖ ͡°)
