\bf 5y^4+11y^2+2\implies 5(y^2)^2+11y^2+2\implies (5y^2+1)(y^2+2)

For this case we must factor the following polynomial:

5y ^ 4 + 11y ^ 2 + 2

We rewrite y ^ 4as (y^ 2) ^ 2:

5 (y ^ 2) ^ 2 + 11y ^ 2 + 2

We make a change of variable:

u = y ^ 2

We replace:

5u ^ + 11u + 2

we rewrite the middle term as a sum of two terms whose product of 5 * 2 = 10 and the sum of 11.

So:

5u ^ 2 + (1 + 10) u + 2

We apply distributive property:

5u ^ 2 + u + 10u + 2

We factor the highest common denominator of each group.

(5u ^ 2 + u) + (10u + 2)\\u (5u + 1) +2 (5u + 1)

We factor again:

(u + 2) (5u + 1)

Returning the change:

(y ^ 2 + 2) (5y ^ 2 + 1)

ANswer:

(y ^ 2 + 2) (5y ^ 2 + 1)

Henry's uncle from Japan promised to give him 35 g of gold. The local jewelry exchange will buy gold for $1224 per ounce. How mu
galina1969 [7]

Answer:

$1530

Step-by-step explanation:

First of all, it is required to convert 35g of gold into ounce.

Since,

1 oz = 28 g

or, we can write,

1 g = \frac{1}{28} oz

Now, for 35 g of gold, we can write,

35 * 1 g = 35 * \frac{1}{28} oz\\35 g = 1.25 oz

Since, local jewelry will buy at $ 1224 per oz, and we have 1.25 oz of gold, so,

1.25 * 1244\\$1530
