You and your friend are selling raffle tickets for a new laptop. you sell 14 more tickets than you friend sells. together, you and your friend sell 58 tickets.

you sold 36 tickets and your friend sold 22 tickets

Step-by-step explanation:

Assume your friend sold x tickets

And you sold (x+14) tickets because the question says you sold 14 more than your friend to have a combined sales of 58tickets

x + (x +14) = 58

2x+14= 58

2x=58-14

2x=44

x=22tickets which your friend sold

X+14= 22+14= 36tickets which you sold

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.
