suppose that f(x)=-x^3 - 3x^2 - 2x +1 and g(x)=2x^3 + x^2 + x + 1. Find f(x) + g(x). Hence, factorise f(x) + g(x) completely given that (x-1) is one of its factor.

3100

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:
