Answer:

  a = 36

Step-by-step explanation:

A stationary point is where the function derivative is zero. Here, we have ...

  y' = 2kx -16/x^2 = 0

For x = 2/3, this is ...

  4/3k -16/(4/9) = 0

  4/3k = 36

  k = 27

Then the value of y at that point is ...

  y = 27(2/3)^2 + 16/(2/3) = 12 +24 = 36

The stationary point of interest is (2/3, a) = (2/3, 36). a = 36.

What equation results from completing of the square and then factoring? X^2+4x=5
andre [41]

Answer:

(x-1)(x+5)=0

x=1; x=-5

Step-by-step explanation:

x²+4x=5

x²+4x+2²=5+2²

(x+2)²=3²

(x+2)²-3²=0

(x+2-3)(x+2+3)=0

(x-1)(x+5)=0

(x-1)=0 ; x=1

(x+5)=0;  x= - 5

A.\\2x^2c^2+3xc^2-35c^2=c^2(2x^2+3x-35)=c^2(2x^2+10x-7x-35)\\\\=c^2[2x(x+5)-7(x+5)]=c^2(x+5)(2x-7)


B.\\x^2+20x+100=x^2+10x+10x+100=x(x+10)+10(x+10)\\\\=(x+10)(x+10)=(x+10)^2
