Answer:

\large\boxed{x^2+8x+19=0\Rightarrow(x+4)^2=-3}

Step-by-step explanation:

x^2+8x+19=0\qquad\text{subtract 19 from both sides}\\\\x^2+8x=-19\\\\x^2+2(x)(4)=-19\qquad\text{add}\ 4^2\ \text{to both sides}\\\\x^2+2(x)(4)+4^2=-19+4^2\qquad\text{use}\ (a+b)^2=a^2+2ab+b^2\\\\(x+4)^2=-3

1. Write your own word problem and share it with the group.
Yuki888 [10]

The solution of the word problem is a = 2

Word Problems are mathematical problems presented in complete languages, rather than in mathematical notations.

Example: Let a number is divided by half, the result is added to itself to give 6, what is the number?

Solution: Let the number be a

Now, dividing a by half, we get

a ÷ \frac{1}{2} = 2a

Now, adding the result to the number itself, we will get 6 i.e.,

2a + a = 6

3a = 6

Dividing both the sides by 3, we get

a = 2

Therefore, the solution is a = 2

Complete question: Write your own word problem and share it with the group. Then translate your problem into its resulting math equation. What steps would you then follow to solve for the variable?
