Ink in blue are notes and equations you need to know.
The answer is C.
39-5/ 21-4 = 2
26. 2x^2 +4x -10 = 0 (-4 + - (root(4^2 - 4*2*-10)))/2*2 =
(-4 + - (root(96)))/4
(-4 + (root(96)))/4 ≈ 1.45
(-4 - (root(96)))/4 ≈ -3.45
27. f(x) = 0 when any of the components that multiply together equal 0 for this function therefore x -2 = 0 x +3 = 0 x -5 = 0 so f(x) = 0 when x = 2, -3 or 5
28. It looks like it shows you how to do it
Given:
The polynomials are:


To find:
The completely simplified sum of the polynomials.
Solution:
We have,


The sum of given polynomials is:


Therefore, the sum of the given polynomials is
. It is a polynomial with degree 6 and leading coefficient -2.
