Step-by-step explanation:
Root of the function, where y = 0
f(x) = x² + 2x - 1
0 = x² + 2x - 1
x² + 2x - 1 = 0
x² + 2x = 1
x² + 2x + 1 = 1 + 1
(x + 1)² = 2
x + 1 = ±√2
x = -1 ± √2
Roots → x = -1 ± √2
Answer:
64°
Step-by-step explanation:
We know that a right angle is 90°
so we do 90° - 26° = 64°
Answer:
(x - 6)(x + 4)
Step-by-step explanation:
x^2 -2x-24
-24 = -6 * 4
- 6 + 4 = -2
So
x^2 -2x-24 = (x - 6)(x + 4)
