Solve for x over the real numbers:
x^2 - 4 x - 5 = 0
The left hand side factors into a product with two terms:
(x - 5) (x + 1) = 0
Split into two equations:
x - 5 = 0 or x + 1 = 0
Add 5 to both sides:
x = 5 or x + 1 = 0
Subtract 1 from both sides:
Answer: x = 5 or x = -1
Answer:
A and C
Step-by-step explanation:
A is correct because converting the percentage to decimal form will give you the value of that percentage, and 62% will be the same as 0.62 in decimal form.
C is the same in a less simplified form because 62/100 = 0.62, so it is the same as A when you convert it to decimal form, 0.62 · 45.
