If a polynomial has four terms, 3x3 + 5x + 6x2 + 10, which factoring method can be considered? perfect-square trinomial difference of squares factor by grouping sum of cubes

Since it is a cubic polynomial (largest exponent is 3) then you cannot use any of the square polynomial methods. You will need to use Grouping.

3x³ + 6x² + 5x + 10

3x²( x + 2) + 5(x + 2) factored out the common factor of the 1st and 2nd pairs

(3x² + 5) (x + 2) the 1st and 2nd pairs have a common factor of (x + 2)

Grouping

C. factor by grouping

hope this helps! :o)

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:
