Is g(x) = (x-1)(x+1)(x-3i)(x+3i) the factored form of f(x) = x^4+8x^2-9

Answers

Answer:

Yes

Step-by-step explanation:

(x-1)(x+1)(x-3i)(x+3i)

FOIL ( x-1) (x+1) = x^2 -x+x-1 = x^2 -1

FOIL (x-3i)(x+3i) = x^2 +3ix -3ix -9i^2 = x^2 -9(-1) = x^2 +9

(x-1)(x+1)(x-3i)(x+3i) = (x^2 -1) (x^2 +9)

FOIL again

x^4 +9x^2 -x^2 -9

x^2 +8x^2 -9

This is the factored form

Which answer is a solution of the equation?2x + y = 5

A. 5
B. (1, 2)
C. (2, -1)
D. (3, -1)

Thank you everyone!

Answers

2x + y = 5

Put the coordinates of the points to the equation and check it:

A. 5 - not make sense

B. (1, 2) - x = 1, y = 2

2(1) + 2 = 2 + 2 = 4 ≠ 5 NOT

C. (2, -1) - x = 2, y = -1

2(2) + (-1) = 4 - 1 = 2 ≠ 5 NOT

D. (3, -1) - x = 3, y = -1

2(3) + (-1) = 6 - 1 = 5 YES

Answer: D. (3, -1).

Please help! !!!!!!50 POINTS!!!!!!! Question bellow!!

Answers

Area = πr²
Area = 3.14* 6²
A = 3.14 * 36
A = 113.04

Now find the area of the other one.

Area = πr²
A = 3.14 * 0.75²
A = 1.76625

Now subtract them.

113.04 - 1.76625 = 111.27375
Now, we have our answer: A = 111.27375

However, I don't see why they told you to have an exact answer for the area. You can't have an exact answer when you use 3.14 for pi.

Answer:

Area = πr²

Area = 3.14* 6²

A = 3.14 * 36

A = 113.04

Now find the area of the other one.

Area = πr²

A = 3.14 * 0.75²

A = 1.76625
