x^2-10x+24>=0
Let's solve in ℝ: x2 -10x + 24 >= 0
You can rephrase the expression into: (x -5)2 -1
(x -5)2 -1 >= 0
You can factorize this expression into: ((x -5) -1)·((x -5) + 1)
Let's solve in ℝ: ((x -5) -1)·((x -5) + 1) >= 0
ℹ-5 -1 = -6‖-5 + 1 = -4
(x -6)·(x -4)
Let's solve in ℝ: x -6 >= 0
Solution found: x >= 6
Let's solve in ℝ: x -4 >= 0
Solution obtained: x >= 4
Let's build the table of the different terms to determine the global solution:
x-∞ 4 6 +∞
x -6--0+
x -4-0++
x2 -10x + 24+0-0+
▶Solution obtained: x ∈ (-∞, 4] ∪ [6, +∞)
