Solve the equation by completing the square and then solving for x. 1. x^2-6x=12 2. 2x^2-24x=-20

Paraphin [41]

Answer: (x - 3)² = 21

Step-by-step explanation:

x² - 6x + ____ = 12 + ____

↓ ↑ ↑

$\frac{-6}{2} = (-3)^{2}$

x² - 6x + 9 = 12 + 9

(x - 3)² = 21

*******************************************************

Answer: (x - 6)² = 26

Step-by-step explanation:

2x² - 24x = -20

÷2 ÷2 ÷2

x² - 12x = -10

x² - 12x + ____ = -10 + ____

↓ ↑ ↑

$\frac{-12}{2} = (-6)^{2}$

x² - 12x + 36 = -10 + 36

(x - 6)² = 26

Mystery number: The number is less than 190000 and greater than 180000.

Kipish [7]

The answer to it is
180, 000 <n> 190, 000
180,000 + 2000 = n = 5000-187, 000
182,000 = n = 182, 000
Or,
180, 000 <n> 190,000
n + 5000= 187, 000 n – 2000 = 180, 000
n= 187, 000- 5000 n = 180, 000 + 2000
n= 182, 000 n= 182, 000

Vedmedyk [2.9K]

Answer:

1.A matrix is a rectangular array of numbers, symbols, or expressions, arranged in rows and columns.

Solution given:

We have

Sin² $\theta$ -Cos ² $\theta$ =1

Sin² $\theta$ =1+Cos² $\theta$

Sin $\theta$ = $\sqrt{1-Cos²\theta}$

4Tan² $\theta$ +4Cot² $\theta$ -3Tan² $\theta$ -3Cot² $\theta$

4Tan² $\theta$ -3Tan² $\theta$ +4Cot² $\theta$ -3Cot² $\theta$

Tan² $\theta$ -Cot² $\theta$
