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

Factor the tribunal into two binomials than solve?
Vanyuwa [196]

Answer:

(x-5)(x-3)=0

x=5 \text{ and } x=3

Step-by-step explanation:

Quadratic Equation given:

x^2-8x+15=0

In order to factor this equation think that we'll have something in the format:(x-a)(x-b)

Once: -a -b = -c

and (-a)(-b)= d

Therefore, we have

(x-5)(x-3)=0

x-5=0\\\text{or}\\x-3=0

x=5 \text{ and } x=3
