Answer:

Polynomial 1. Option B

Polynomial 2. Option A

Polynomial 3. Option C

Polynomial 4. Option D

Step-by-step explanation:

For first polynomial

x² - 8x - 20 by factorizing the polynomial we get

x² - 10x + 2x - 20 = x(x - 10) + 2(x -10) = (x +2)(x - 10)

Therefore Option B is the answer.

for polynomial 2

x² + 8x - 20 = x² + 10x -2x + 20 = x(x + 10)-2(x + 10) = (x-2)(x+10)

Therefore Option A is the answer

for polynomial 3

x² - x - 20 = x² - 5x + 4x -20 = x(x - 5) + 4(x - 5) = (x - 5)(x + 4)

Option C) matches the factors  

for option 4

x² - 9x - 20 By quadratic formula we get the factors prime.

Therefore Option D) matches the same.

Factor each linear expression.if expression can not be factored write cannot be factored.<br> 36x-9
almond37 [142]

Answer:

9(4x - 1)

Step-by-step explanation:

The given linear expression is:

36x - 9

Since, 36 can be written as 9 times 4, we can rewrite the above expression as:

9(4x) - 9

Taking 9 as common, the expression changes to:

9 (4x - 1)

This linear expression can no linger be factorized further.

So,

36x - 9 = 9(4x - 1)

WILL MARK BRAINLIEST!! PLZ HELP!!! 20 POINTS Create a graph of the polynomial function g(x) = (x + 2)(x − 1)(x − 2)
Gennadij [26K]

Answer:

We have: g(x)=(x+2)(x-1)(x-2)

multiply the 3 terms:

  • (x+2)(x-1)(x-2)
  • (x²-4)(x-1)
  • x^3 -x²-4x+4

This is a polynimial function with 2 vertices

The roots are approximatively:

0.8 and -1.5

their images are:

1.9 and 8.8

plot these two vertices and draw some other points

here is a drawing:

Evaluate the following expression. 3^-2
Crazy boy [7]

Answer: The simplified form is \frac{1}{9}

Step-by-step explanation:

Since we have given that

3^{-2}

As we know the  "Exponential law":

a^{-1}=\frac{1}{a^m}

So, it becomes

3^{-2}=\frac{1}{3^2}

Now, at last it becomes,

3^{-2}=\frac{1}{3\times 3}=\frac{1}{9}

Hence, the simplified form is \frac{1}{9}
