Answer:
(x + 3)/(x + 1) .
Step-by-step explanation:
2x^2 + 3x/(2x + 3)(x - 2) - 6 /x^2 - x - 2
= 2x^2 + 3x/(2x + 3)(x - 2) - 6 / (x - 2)(x + 1)
The LCM is (2x + 3)(x - 2)(x + 1) so we have
(2x^2 + 3x)(x + 1) - 6(2x + 3) x( 2x + 3)(x + 1) - 6(2x + 3)
--------------------------------------- = ------------------------------------
(2x + 3)(x - 2)(x + 1) (2x + 3)(x - 2)(x + 1)
(2x + 3)(x(x + 1) - 6) (2x + 3)(x - 2)(x + 3)
= ---------------------------- = --------------------------- = (x + 3)/(x + 1)
(2x + 3)(x - 2)(x + 1) (2x + 3)(x - 2)(x + 1)
The graph of the function will have zero of -2 and 8 respectively
<h3>Quadratic function</h3>
Quadratic functions are function that has a leading degree of 2. Given the quadratic equation
y = x^2 - 6x - 16
Factorize
y = x^2 - 6x - 16
y = x^2 - 8x + 2x - 16
y = x(x - 8) + 2(x-8)
y = (x+2)(x-8)
The graph of the function is attached below

3/4 - 4 z + 5/4 z - 1/2 + 1/2 z
First, put the like terms together:
-4z + 5/4z + 1/2z + 3/4 - 1/2
Find the LCM of the first three to turn them into one massive fraction:
-16/4z + 5/4z + 2/4z + 3/4 - 1/2
Do the same for the last 2 fractions:
-16/4z + 5/4z + 2/4z + 3/4 - 2/4
Simplify everything (keeping like terms in mind)
-9/4z + 1/4
And that's the answer :)

Answer:
4. 3.1% this could be 0% either idk bc 0.031 rounded to nearest 10th is 0
6. 90%
8.10%
