Factor the higher degree polynomial
5y^4 + 11y^2 + 2

For this case we must factor the following polynomial:

We rewrite as :

We make a change of variable:

We replace:

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

So:

We apply distributive property:

We factor the highest common denominator of each group.

We factor again:

Returning the change:

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
