Factor the problem first. So for number one, take out a seven to make it 7(x+4) and factor by subtraction of square roots on the bottom to make it (x-4)(x+4) Then, because there are factors of (x+4) on the top and bottom, cancel them out to make it 7/(x-4)

Im guessing restrictions are the values x cannot be. So you take the denominator factors of (x+4)(x-4) and set them equal to zero. x+4=0 and x-4=0.

so x cannot =4, and -4

Hope this helps you answer the next ones!

Complete the given operation and write the expression in standard form.
Elodia [21]

Step-by-step explanation:

Using synthetic division of polynomials 3x⁴-2x²+4x+9÷x+2. Rewrite the dividend as 3x⁴+0x³-2x²+4x+9

2 | 3 0 -2 4 9

| 6 -12 20 -32

3 -6 10 -16 41

So the quotient is 3x³-6x²+10x-16 with a remainder of 41

Therefore, 3x³-6x²+10x-16+(41/x+2)

Answer:

  y -4 = -2(x -(-11))

Step-by-step explanation:

The point slope formula is ...

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

__

So, the boxes in order from left to right are k, m, h.

The problem statement tells you the point is (-11, 4), so h = -11, k = 4. It also tells you the slope is -2, so m = -2.

Putting these numbers in the required order, we have k = 4, m = -2, h = -11 and the equation of the line is ...

  y-\boxed{4}=\boxed{-2}(x-\boxed{-11})
