Answer:
1. X = 12
2. x = 5 or x = 2
3. x = -1.042
4. x = -2.1415
5. x = -6
Step-by-step explanation:
1. X - 5 - 7 = 0
X - 12 = 0
X = 12
2. x² - 7x + 10 = 0
x² - 5x - 2x + 10 = 0
x(x - 5) - 2(x - 5) = 0
(x - 5) (x - 2) = 0
x - 2 = 0 or x - 5 = 0
3. 4x³ - 6x²- x + 10 = 0
x = -1.042
4. 2x⁵ + 4x⁴ - 3x² - 5x + 9 = 0
x = -2.1415
5. x² + 12x + 36 = 0
(x + 6)² = 0
x + 6 = 0
x = -6
