Answer:
<u>x = √13 - 3</u>
<u>x = -√13 - 3</u>
Step-by-step explanation:
Given :
Solving :
- x² + 6x + 9 - 9 - 4 = 0 [Adding and subtracting 9]
- (x + 3)² - 13 = 0 [Group the square term together]
- (x + 3)² -13 + 13 = 0 + 13 [Add 13 on both sides]
- √(x + 3)² = √13 [Taking square root on both sides]
- x + 3 - 3 = ±√13 - 3 [Subtract 3 from both sides]
- x = ±√13 - 3
Solutions :
- <u>x = √13 - 3</u>
- <u>x = -√13 - 3</u>

Answer:
x ≥ - 5
Step-by-step explanation:
3x - 12≤8x + 13.
3x - 8x ≤ 13+ 12
-5x≤25
x ≥-5
