Need to know this now pls !!! NEED THE PROCESS , TOO!!!<br><br> x squared - 18x = -117

nydimaria [60]

Answer:

x = 9 + 6i or x = 9 - 6i

Step-by-step explanation:

x² - 18x + 117 = 0

Complete the square and solve:

(x - 9)² - 81 + 117 = 0

(x - 9)² + 36 = 0

(x - 9)² = -36

x - 9 = ±sqrt(-36)

x - 9 = ±sqrt(-1).sqrt(36)

i = imaginary number = sqrt(-1)

x - 9 = ±6i

x = 9 ± 6i

There are no real solutions, only imaginary ones

9 + 6i and 9 - 6i

Two times the smaller of two consecutive integers is equal to 2 more than the larger. What is the LARGER integer?

LenaWriter [7]

Answer:

The larger integer is $4$ .

Step-by-step explanation:

Given: Two times the smaller of two consecutive integers is equal to $2$ more than the larger.

To find: The larger integer.

Solution:

Let the two consecutive integers be $x$ and $x+1$ , where the smaller integer is $x$ and larger integer is $x+1$ .

Now, according to question.

Two times the smaller integer $=$ $2$ more than the larger integer.

$\implies 2x=x+1+2$

$\implies 2x-x=3$

$\implies x=3$

So, the smaller integer is $3$ , and the larger integer is $3+1=4.$

Hence, the larger integer is $4.$
