X^2 - 10x +18 (x-a)^2+b

2−10+18(−+)2+

Step-by-step explanation:

18a^2-36ax+19x^2+b-10x

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:
