Answer:
x = 2 or x = 1 or x = -1
Step-by-step explanation:
Solve for x over the real numbers:
x^5 - 4 x^4 + 4 x^3 + 2 x^2 - 5 x + 2 = 0
The left hand side factors into a product with three terms:
(x - 2) (x - 1)^3 (x + 1) = 0
Split into three equations:
x - 2 = 0 or (x - 1)^3 = 0 or x + 1 = 0
Add 2 to both sides:
x = 2 or (x - 1)^3 = 0 or x + 1 = 0
Take cube roots of both sides:
x = 2 or x - 1 = 0 or x + 1 = 0
Add 1 to both sides:
x = 2 or x = 1 or x + 1 = 0
Subtract 1 from both sides:
Answer: x = 2 or x = 1 or x = -1

Step-by-step explanation:
Angle Formed by Two Secants= 1/2(difference of Intercepted Arcs)
<1 = 1/2(104-56)
<1 = 1/2(48)
<1 = 24
Answer: -35+28n
Step-by-step explanation:
-7*5=-35
-7*-4n=+28n
Answer:
Step 1:
Addition is commutative
A + B = B + A
So the terms can be rearranged
Step 4:
2x(2x - 3) + 5(2x - 3)
Since (2x - 3) is common to both terms,
You can take it common
(2x - 3)(2x + 5)
This can be proved verified using distribution property
(2x - 3)(2x + 5) is the same as
(2x + 5)(2x - 3) because multiplication is commutative
