Step-by-step explanation:
Answer:
x² + 4x + 20 = 12x - 5
x² + 4x - 12x + 20 + 5 = 0
x² - 8x + 25 = 0
Δ = √b² - 4ac
= √(-8)² - 4×1×25
= √64-100
= √(-36)
x ∉ R
Answer:
3/-2
Step-by-step explanation:
(3x) km/3 -2x=4 (x3) times 3 on both sides because you need to get the x by itself and your dividing so the opposite of dividing is multiplying.
9km - 2x = 12
-9 -9 subtract on both sides
-2x = 3
-2 -2 divide on both sides.
so x= 3/-2
I'm in algebra too, and i'm relearning it, so hope i have helped you in anywy and if i haven't I'm sorry.
