You meant to say x^2 - 49 and the second binomial is x^2 - 16.
x^2 - 49 = (x - 7) (x + 7).
Set each factor to 0 and solve for x individually.
x - 7 = 0
x = 7
x + 7 = 0
x = -7
Do the same for x^2 - 16.
Here is the set up:
x^2 - 16 = (x - 4) (x + 4).
Take it from here.
Answer:
3.)138
4.) 149
Step-by-step explanation:
you add the two inside measures together.
3/7 + 2/7 = 5/7
5/7 = h/14
5/7 x 2 = 10/14
10/14 = h/14
h = 10
Answer:
- Sadie didn't split the a^7 term into the largest even exponent and the remaining factor. She stopped at a^2.

Step-by-step explanation:

Answer:
x=4
Step-by-step explanation:
12x-48 12*(4)
12=0
x=4=0
Add 4 to both sides of the equation
So x=4
12*4+25
48+25
73
