I'm assuming that there is another root which should be -SQRT(11)
f(x) = x(x-4)(x+SQRT(11))(x-SQRT(11)
Then
f(x) = x^4 -4x^3 - 11x^2 +44x

Step-by-step explanation:</h2>
<h3>Multiply the values.</h3>
![1.3*1.3=1.69](https://tex.z-dn.net/?f=1.3%2A1.3%3D1.69)
<h3>Result.</h3>
1.69.
14/18 because you multiply by 2 on each number.
Step-by-step explanation:
9.9²
(10-0.1)²
= 10² -2 (10) (0.1) + 0.1²
= 100 -2 + 0.01
= 98.01
Hope it helps you
