Answer:
2/14
Step-by-step explanation:
I think you double both, but I'm, not sure :)
X² - 8x = -10
to have a complete square, we must have this format:
a² + 2ab + b²
a² = x²
2ab = -8x ⇒ 2(x)(-4)
b² = -4² = 16
x² - 8x + 16 = -10 + 16
x² - 8x + 16 = +6
(x-4)² - 6 = 0
Both sides must have an additional value of 16.
Answer:
+0.1
Step-by-step explanation:
Note that -4.5 + 4.4 = -0.1.
Adding 0.1 to -0.1 results in 0.
The unknown was +0.1.
