Answer:
5x^2+22x-12 x cannot be -5, -4, -2
(x+5)(x+4)(x+2)
Step-by-step explanation:
In order to solve this, your denominator must be the same. Let's start by writing out the two different quadratic formulas:
x^2 + 6x + 8 <-- This should factor out to (x+4)(x+2)
x^2 + 7x + 10 <-- This should factor out to (x+5)(x+2)
Now that you have factored out the two quadratics, plug them into the equation.
5x - 3
(x+4)(x+2) (x+5)(x+2)
Now as we know, -2 cannot be x because it will turn the entire equation undefined. Multiple top and bottom with (x+5) on the right side and (x+4) on the left side.
5x (x+5) - 3(x+4)
(x+5)(x+4)(x+2) (x+5)(x+4)(x+2)
Focus on the top. 5x(x+5) will turn out to be 5x^2+25x. 3(x+4) will turn out to be 3x+12. Combine the two equations because now they are equal to each other and do the subtraction:
5x^2+25x - (3x+12) = 5x^2+22x-12 x cannot be -5, -4, -2
(x+5)(x+4)(x+2) (x+5)(x+4)(x+2)
If you are trying to simplify it, I think it would be -22<36. Im not sure because I haven't learned this that much in school yet. I do know that if you are confused on how to do it, you can use...

This is the order that you do to solve the problem, For example,
P stands for Parentheses
E stands for Exponents
M stands for Multiplication
D stands for Division
A stands for Addition
S stands for Subtraction
This is the order of how you solve the problem. If one of the things aren't in the particular problem, then skip that certain step. For example if Addition wasn't in the problem, then you would skip the A. I hope this helps!
The value of x when y is equal to 8 would be 2/3.
