can someone explain to me how to use "squared"? I do 2+2 and its four. but when I do 3+3 and I get 6, my brother tells me that's not squared. can you help me out?

Answer:

x = - 2 or x = - 8

Step-by-step explanation:

Given

2(x² + 10x) = - 32 ( divide both sides by 2 )

x² + 10x = - 16

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(5)x + 25 = - 16 + 25

(x + 5)² = 9 ( take the square root of both sides )

x + 5 = ± = ± 3 ( subtract 5 from both sides )

x = - 5 ± 3, thus

x = - 5 + 3 = - 2 or x = - 5 - 3 = - 8

The requried 3 divided by 14 in fraction form is 3/14.

What is the fraction?

A fraction is a mathematical concept that can be used to express a portion of a whole or a number that can be written as the ratio of two integers. In a fraction, the top number is referred to as the numerator, while the bottom number is referred to as the denominator.

Here,
As mentioned in the question, 3 divided by 14 in fraction form is given as,
a = 3, b  = 14
fraction = a/b
fraction = 3/14

Thus, the requried 3 divided by 14 in fraction form is 3/14.

Answer: That would be demonstrated as 3/14, or 3 over 14

Step-by-step explanation:

The numerator is the number being divided, and the denominator is the divider. So if I were to write 1/2, 1 is being divided by 2, which results with .50.  .50 is half of the whole number 1, make sense? :)
