### The Girl Who Played with Fire

I'm reading the second book of the Millennium trilogy by Stieg Larson. The story starts with a paragraph about equations. Can you complete the gaps? Use comments and write your name:

PART 1: Irregular Equations
DECEMBER 16–20

Equations are classified by the highest (a)________ (value of the exponent) of their unknowns. If this is one, the equation is of (b)________  degree. If this is (c)________ , the (d)________  is of second degree, and so on. Equations of higher degree than one yield multiple possible values for their unknown quantities. These values are known as (e)________ .
The first-degree equation (the linear equation):

3x−9 = 0 (root: x = ______)

Equations are classified by the highest (a)_____power___ (value of the exponent) of their unknowns. If this is one, the equation is of (b)__first______ degree. If this is (c)___second_____ , the (d)_power_______ is of second degree, and so on. Equations of higher degree than one yield multiple possible values for their unknown quantities. These values are known as (e)__roots______ .

13. Equations are classified by the highest (a)power (value of the exponent) of their unknowns. If this is one, the equation is of (b)first degree. If this is (c)two, the (d)equation is of second degree, and so on. Equations of higher degree than one yield multiple possible values for their unknown quantities. These values are known as (e)roots.
The first-degree equation (the linear equation):
