Answer:

The answer is 3 , 1 , 2 .

Step-by-step explanation:

I will give an example.

e.g.

x² + 3x + 2

Step 3 :

Set the equation equal to zero :

x² + 3x + 2 = 0

Step 1 :

Completely factor the equation :

x² + x + 2x + 2 = 0

x(x+1) + 2(x+1) = 0

(x+2)(x+1) = 0

Step 2 :

Set each factor equal zero and then solve for the variable :

(x+2)(x+1) = 0

x + 2 = 0

x = -2

x + 1 = 0

x = -1

Cloud [144]
54 is the hypotenuse because it is the longest side. Square all of the sides. So 54^2=2916
51^2=2601
22^2=484
Now you have 2916=2601+484
Add the two and they will be greater than 2916. Because of that, you will have an acute triangle because 22^2+51^2>54^2
In short, its B
