Assuming that $y\neq 1/2,$ simplify the expression$$\dfrac{12y^3-6y^2}{2y-1 }.$$

Given:

The expression is

, where .

To find:

The simplified form of the given expression.

Solution:

We have,

Taking out the common factors from the numerator, we get

Cancel out the common factors from numerator and denominator.

Therefore, the simplified form of the given expression is .

step-by-step explanation:

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
