Hello :
let : x = s so : y = x-1
all points is the line passe by : (1, 0) of the slope 1
What is this? may I ask? did you mean to attach a photo?
Answer:
Step-by-step explanation:
9x⁴ – 2x² – 7 = 0
Let's say that u = x²:
9u² – 2u – 7 = 0
Factor:
(u – 1) (9u + 7) = 0
u = 1, -7/9
Since u = x²:
x² = 1, -7/9
x = ±1, ±i √(7/9)
Answer: False.
