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)

Find the zeros of the function by rewriting the function in intercept form

y=3x^2+2x\\&#10;y=x(3x+2)\\&#10;y=x(x+\frac{2}{3})\\&#10;x=0 \vee x=-\frac{2}{3}\\\\&#10;f(x)=5x^2-25x+30\\&#10;f(x)=5(x^2-5x+6)\\&#10;f(x)=5(x^2-2x-3x+6)\\&#10;f(x)=5(x(x-2)-3(x-2))\\&#10;f(x)=5(x-3)(x-2)\\&#10;x=3 \vee x=2&#10;&#10;

Paul's dad made a turkey pot pie for dinner on Wednesday the family ate 4/8 of the pie. on Thursday after school,Paul ate 2/16 o
Drupady [299]
You would add the 2 fractions. Since 2/16 equals 1/8 you could add 1/8 plus 4/8. That will give you 5/8. After all that you subtract 5/8 from 8/8, which will give you 3/8.
