- Terms/Coefficients
- Factoring
- Solving quadratics
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = x² - x - 12
<u>Step 2: Solve for </u><em><u>x</u></em>
- Factor: (x - 4)(x + 3) = 0
- Solve: x = 4, -3
Answer:
-√7
Step-by-step explanation:
radical roots always occur in pairs.
√7 is a root ,so -√7 should also be a root of polynomial f(x)
21 times because you need 7/4=1 gallon and 3/4 just for one and 7x3 =21 so need 21/4
7x1=7, then 4x1/4= 4x1=4 divided by 4= 1. Then subtract 7- 1= 6
