Sagot :

Answer:

1. 8/8 or 1

2. 11/24

3. 7x+7 or 7(x+1) if factored version is needed

4. 5x^2-4x-5

1. no solution required

2. lcd is 24

5/8 × 3/3 =15/24

1/6 × 4/4 = 4/24

15/24-4/24=11/24

since the lcd is 24, you should look for numbers you can multiply to the given to make the denominators 24

3. 3x+5x-x+7

3x+5x=8x

8x-x=7x

7x+7

4. 5x^2-6x+2x-5

-6x+2x=-4x

5x^2-4x-5
