Answer:
Step-by-step explanation:
Given
Solving for x
- 12x + 16 = 50x - 3
- 50x - 12x = 16 + 3
- 38x = 19
- x = 19/38
- x = 1/2

Answer:
f(x)=x^3-3x^2+25x-75
Step-by-step explanation:
Solve for x:
x^3 - 3 x^2 + 25 x - 75 = 0
The left hand side factors into a product with two terms:
(x - 3) (x^2 + 25) = 0
Split into two equations:
x - 3 = 0 or x^2 + 25 = 0
Add 3 to both sides:
x = 3 or x^2 + 25 = 0
Subtract 25 from both sides:
x = 3 or x^2 = -25
Take the square root of both sides:
Answer: x = 3 or x = 5 i or x = -5 i
