Which of the following would be the most logical first step to solving this
quadratic equation?
x2 - 4x + 16 = 2
a. take the square root of both sides.
b. subtract 2 from both sides.
estate
c. factor the left side into a perfect square.
d. divide both sides by x

The correct option is B:

Subtract 2 from both sides

Step-by-step explanation:

We have the equation x²-4x+16=2

The first step to solve this equation is:

Subtract 2 from both sides

We get;

x²-4x+16=2

x²-4x+16-2=2-2

x²-4x+14=0

Now this is the quadratic equation. You can use quadratic formula to solve this equation

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
