<u>Answer: </u>

The factor of 9 x^{4}+12 x^{3}+21 x^{2} \text { is } 3 x^{2}\left(3 x^{2}+4 x+7\right)

<u>Solution: </u>

From question given that the equation is

9 x^{4}+12 x^{3}+21 x^{2}

We have to find the factors of the given equation.

By taking 3 as a common term in above expression,

=3\left(3 x^{4}+4 x^{3}+7 x^{2}\right)

By taking “x” as a common term in above expression, we get equation as

=3 x\left(3 x^{3}+4 x^{2}+7 x\right)

Again taking “x” as a common term in above expression, we get

=3 x^{2}\left(3 x^{2}+4 x+7\right)

\left(3 x^{2}+4 x+7\right) cannot be factorized.(imaginary roots)

Hence factor of 9 x^{4}+12 x^{3}+21 x^{2} \text { is } 3 x^{2}\left(3 x^{2}+4 x+7\right)

Darcy bought 1 2 pound of cheese and 5 6 pound of hamburger for a barbecue. Use the numbers to compare the amounts of cheese and
Zepler [3.9K]

Answer:

  • Darcy bought more Hamburgers than Cheese
  • 1/2 pound of cheese < 5/6 pounds of Hamburgers

Step-by-step explanation:

Darcy bought 1/2 pounds of cheese and 5/6 pounds of hamburgers.

Convert these to decimals to be sure which is larger:

= 1/2                                                               = 5/6

= 0.5 pounds                                                 = 0.83 pounds

The hamburgers are therefore more so the comparison would look like:

1/2 pound of cheese < 5/6 pounds of hamburgers
