Solve x^2 - 4x - 7 = 0 by completing the square. What are the solutions?
sergejj [24]

Answer:

x = ±√11 +2

Step-by-step explanation:

Given in the question an equation,

x²- 4x - 7 = 0

Step 1

take 7 to the right side of equation

x²- 4x = 7

Step 2

To create a trinomial square on the left side of the equation, find a value that is equal to the square of half of b, the coefficient of x

2ab = -4x

2xb = -4x

b = -2

Step 3

Take square of b and add it to each side of the equation.

x²- 4x + (-2)²= 7 + (-2)²

x²- 4x + 4 = 7 + 4

x²- 4x + 4 = 11

Step 4

Factor the perfect trinomial square

(x−2)² = 11

Step 5

take square root on both sides

√(x−2)² = √11

(x-2) = ±√11

x = ±√11 +2

Please help and explain.
Rashid [163]

Answer:

-3/2

Step-by-step explanation:

Use formula (y2 - y1)/(x2 - x1)

Take points (-8, 4) and (-6, 1)

Use the formula:

y2 = 1

y1 = 4

x2 = -6

x1 = -8

(1 - 4)/(-6 - (-8))

= -3/(-6 + 8)

= -3/2
