What number must you add to complete the square? x^2+26x=33
katrin2010 [14]

Answer:

Must add: 202

Step-by-step explanation:

The \ formula \ for \ perfect \ square => (a + b)^2  = a^2 + 2ab + b^2

a = x

2ab = 26x

2ab = 26a  [ substitute a instead of x]

b = \frac{26a}{2a}

b= 13

So,

  (x + 13)^2 = x^2 + 26x + 169

But given equation is :

       x^2 + 26x = 33\  =>  \ x^2 + 26x -33 = 0

We have find the difference between 169 and -33 to get the number that should be added to get the perfect square.

That is , 169 - (-33) = 202

Therefore ,

   x^2 + 26x -33 + 202 \ makes \ given \ equation  \ a \ perfect \ square

vredina [299]
$12 x .20 = $2.40 

12 - 2.40 = $9.60

$9.60 x .07 = $0.67 

$9.60 + $0.67 = $10.27 

Total price (including tax): $10.27
