Mathswatch - solving quadratuc equations question plz help!

(X+4)(x-11)

X= -4

X = 11

Step-by-step explanation:

x^2-7x - 34=10

x^2 -7x -34 -10 =0

x^2 - 7x - 44 = 0

The number in the middle is -7 and the other number is -44

Find two numbers that when multiply = -44 and when added= -7

4 * -11 = -44 and 4 + -11 = -7

(x+4)(x-11)

x + 4 = 0

x = -4 and

x -11 = 0

x = 11

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:
