How to factor 8^2+4−12

4 ( x + 1 ) ( 2 x − 3 )

8 x 2 − 4 x − 12 8x2-4x-12 Factor 4 4 out of 8 x 2 − 4 x − 12 8x2-4x-12 .

Hey there!

8^2 + 4 - 12

8^2

= 8 * 8

= 64

64 + 4 - 12

64 + 4 = 68

68 - 12

= 56

56

Good luck on your assignment and enjoy your day!

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:
