What number must be added to x2 8x to complete the square?
To complete the square for the expression ( x^2 + 8x ), first take half of the coefficient of ( x ) (which is 8), square it, and add it. Half of 8 is 4, and squaring it gives ( 4^2 = 16 ). Therefore, the number that must be added to ( x^2 + 8x ) to complete the square is 16. Thus, the completed square form is ( (x + 4)^2 ).
What number must be added to x2 plus 9x to complete the square?
To complete the square for the expression (x^2 + 9x), take half of the coefficient of (x) (which is 9), square it, and add that value. Half of 9 is (4.5), and squaring it gives (20.25). Therefore, the number that must be added is (20.25). Thus, the completed square form is ((x + 4.5)^2).
What number completes the square x2 26x33?
To complete the square for the expression (x^2 + 26x + 33), we need to focus on the (x^2 + 26x) part. We take half of the coefficient of (x), which is (26), giving us (13), and then square it to get (169). Therefore, the number that completes the square is (169). The full expression can be rewritten as ((x + 13)^2 - 136) after adjusting for the added square.

What number must be added to the polynomial to complete the square x2 - 20x?
Adding 100 completes the square. { I wonder why you want to complete the square when the expression already factors as x(x-20) }.
What number must be added to x2 plus 9x to complete the square?
To complete the square for the expression (x^2 + 9x), take half of the coefficient of (x) (which is 9), square it, and add that value. Half of 9 is (4.5), and squaring it gives (20.25). Therefore, the number that must be added is (20.25). Thus, the completed square form is ((x + 4.5)^2).

Can a non-radical number be added to a radical?
An expression such as root(3) + 2 (square root of 3, added to 2) can not be simplified. Of course, you can convert the square root to a decimal and then add, to get an approximate result.
What number must be added to both sides of the equation to complete the square x2 12x-6?
To complete the square for the expression (x^2 + 12x - 6), we need to focus on the (x^2 + 12x) part. We take half of the coefficient of (x) (which is 12), square it, and add it to both sides. Half of 12 is 6, and squaring it gives us 36. Therefore, we must add 36 to both sides of the equation.
