Dividing negative exponents is almost the same as multiplying them, except you're doing the opposite: subtracting where you would have added and dividing where you would have multiplied. If the bases are the same, subtract the exponents. Remember to flip the exponent and make it positive, if needed.

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

What is equivalent to 3 radical 8
klemol [59]

Answer:

Equivalent 3\sqrt{8}=6\sqrt{2}

Step-by-step explanation:

Given: 3 radical 8

Mathematically 3 radical 8 can be written as 3\sqrt{8}

We have to find an equivalent to 3\sqrt{8}.

Given expression can be written as ,

3\sqrt{8}=3\sqrt{4 \times 2}

On further simplification, we get,

3\sqrt{4 \times 2}=3(\sqrt{4} \sqrt{2} )

We know \sqrt{4}=2

further simplification gives,

3\sqrt{8}=6\sqrt{2}

Thus, Equivalent 3\sqrt{8}=6\sqrt{2}
