We can find roots by setting f(x) = 0 --> x^4 - x^3 - 13x^2 + x + 12 = 0.
Factoring f(x) to make things easier for us gives us (x - 1)(x + 1)(x - 4)(x + 3), which, equal to 0, gives us the ability to set each set of parentheses = 0.
x - 1 = 0 gives us x = 1.
x + 1 = 0 --> x = -1.
x - 4 = 0 --> x = 4.
x + 3 = 0 --> x = -3.
our roots are x = 1, -1, 4, and -3.
Answer:
This is an percentage change question, by any chance you have a maths textbook, search for units that contains the topic: Percentage Change/Percentage. Now, let's get solving! :D
Step-by-step explanation:
First of all, you multiply 7% with $778,095 which gives: $54,466.65 (This is your commission/Answer)
<em><u>Most currency questions use 1 decimal place,</u></em><em><u> </u></em><em><u>so</u></em><em><u> </u></em><em><u>I recommend you to use this answer: $54,466.7</u></em>
Stay safe and Merry Christmas! :)
