Answer:
It is all determined by how many spaces and which way the decimal point moves.
Step-by-step explanation:
So here are two examples
<em>Example 1:</em>
500000.00
To write this in scientific notation you would move the decimal place to the left.
You would move it 5 digits to the left so the exponent of 10 would be 5
<em>Example 2</em>
0.0000042
Here to write this in scientific notation you move the decimal place to the right.
You would move it 6 digits to the right so the exponent would be -6

Step-by-step explanation:
All of the solutions to the equationare x = 12 and x = -12
Solve:
Common factor -
Divide both sides
Use the quadratic formula
x = 2, x = -2
Thus, This is false..

There are two unique solutions to the equations (x-3)^2 = 16
one variable in matrix = one possible value.
Therefore, x = 7, x = -1
Hence this is True
-------------------------------------------------------------------------------------------------------------
The solutions for the equation 2(x-3)^2-18 = 0 are x = 6 and x = 0
Hence this is false
-------------------------------------------------------------------------------------------------------------
The solutions for the equation 2(x-5)^2-8=0 are x = 7 and x = -7
Add both sides by 8
2(x-5)^2-8+8=0+8
2(x-5)^2=8
(x-5)^2=4
x = 7, x = 3
Hence, this is false
-------------------------------------------------------------------------------------------------------------
The solutions for the equation (x + 3)^2-25 = -8 are x = 2 and x = -8
Hence this is false.
-------------------------------------------------------------------------------------------------------------
The solutions for the equation 2(2x-1)^2=18 are x = 5 and x = -4
x=2, x = -1
Hence this is false.
-------------------------------------------------------------------------------------------------------------
The only solution for equation (2x-1)^2-49=0 is x = 4
x = 4, x = -3
Hence, this is false
-------------------------------------------------------------------------------------------------------------
The solutions for the equation 3(x+2)^2 - 3 = 0 are x = -3 and x = -1
x = -1, x = -3
Hence, this is true
-------------------------------------------------------------------------------------------------------------
The solutions for the equation 5x^2 - 180 = 0 are x = 6 and x = -6
Add 180 to both sides
x = 6, x = -6
Hence, this is true.
