Answer:
x = 36
Step-by-step explanation:

Subtract x and 36 from both sides.

Divide both sides by -1.

Square both sides.

Subtract 144x from both sides.

Factor the right side.



Since the solution of the equation involved squaring both sides, we musty check the answer for possible extraneous solutions.
Check x = 36:





Since 0 = 0 is a true statement, the solution x = 36 is a valid solution.
Answer:
D) x = ± 2√5 - 4
Step-by-step explanation:
2x² + 16x - 8 = 0
Yah, i plugged this into m a t h w a y

Answer:
m = - 8 ± 6
Step-by-step explanation:
Given
m² + 16m - 8 = 0 ( add 8 to both sides )
m² + 16m = 8
To complete the square
add ( half the coefficient of the m- term )² to both sides
m² + 2(8)m + 64 = 8 + 64
(m + 8)² = 72 ( take the square root of both sides )
m + 8 = ±
= ±
= ± 6
Subtract 8 from both sides
m = - 8 ± 6
