I M not sure this is is right this is scientific notation
Drupady [299]
(4.18 × 9) = 37.62
10^-4 × 10^-4 = 10^-8
Then since you need to move the decimal over to make it in scientific notation, you add 1 to the 10^-8 , then you get 10^-7. The problem in scientific notation is 3.726×10^-7.

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number? x = –1 and x =
andrey2020 [161]

we have

f(x)=x^{2}-2x-3

Find the roots

Equate the function to zero

x^{2}-2x-3=0

Group terms that contain the same variable, and move the constant to the opposite side of the equation

x^{2}-2x=3

Complete the square. Remember to balance the equation by adding the same constants to each side.

x^{2}-2x+1=3+1

x^{2}-2x+1=4

Rewrite as perfect squares

(x-1)^{2}=4

Square root both sides

(x-1)=(+/-)2

x=1(+/-)2

x=1+2=3

x=1-2=-1

therefore

<u>the answer is</u>

x=3
