Factor by grouping.
0 = (x^3 +4x^2) +(9x +36) = x^2(x+4) +9(x+4) = (x^2+9)(x+4)
The first factor is the difference of squares (in complex numbers), so the form for factoring that can be used:
a^2 - b^2 = (a -b)(a +b)
Here, a=x, b=3i.
Then the factorization in complex numbers is
0 = (x -3i)(x +3i)(x +4)
Solutions are the values of x that make these factors be zero.
x = -4, -3i, 3i

Answer:
25%
Step-by-step explanation:
Lets figure out how many students total in Lorenzo's grade:
7 students + 21 students = <u>28 total students</u>
<u />
We know that we can find the percentage by dividing our value by the total amount and multiplying it by
, which is 1. (Multiplying by 1 does not change anything, which is why we choose to do this.)
Taking our known values,

<em>Therefore, </em><em>25%</em><em> of students voted for the athlete.</em>
