Linh decides to put 1/6 of her paycheck into her savings account. use the
model to write an equation that represents the amount of her paycheck in
terms of the amount put into savings. then use the equation to determine
the amount of her paycheck. use 'x' as the variable.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =    

hope this you and
