We have
x² + 24x = 17                          (1)

Note that
(x + 12)² = x² + 24x + 144
By adding 144 to the left side of equation (1), it becomes a perfect square.

Therefore
x² + 24x = (x+12)² - 144         (2)

Substitute (2) into (1).
(x + 12)² - 144 = 17 
(x + 12)² = 17 +144
(x + 12)² = 161

Answer:
We added 144 to the left side of equation (1) in order to make it a perfect square.

Solve this equation 3(2x+3)=9
Scilla [17]

Answer:

0

Step-by-step explanation:

Isolate the variable x. First, distribute 3 to all terms within the parenthesis.

3(2x + 3) = 3(2x) + 3(3) = 6x + 9

6x + 9 = 9

Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. First, subtract 9 from both sides.

6x + 9 (-9) = 9 (-9)

6x = 0

Divide 6 from both sides.

(6x)/6 = (0)/6

x = 0

0 is your answer.
