Add _____ to each side x2 – 8x = 9 to complete the square.

zhuklara [117]

Answer:

The correct answer is 25

Step-by-step explanation:

It is given a quadratic equation,

x² – 8x = 9

<u>To find the number to be added</u>

The given equation be x² – 8x = 9

here we have to add (b/2)² - the square of half the coefficient of x,

Here b = -8

(b/2)² = (-8/2)² = -4² = 16

Add both side with 16

x² – 8x + 16 = 9 + 16

(x - 4)² = 25

(x - 4)² = 5²
