Find the center of the following equation.
x 2 + y 2 + 8 x - 6 y - 15 = 0

Question

1 Answer/Comment

x^2 + y^2 + 8x - 6y - 15 = 0

(x + 4)^2 - 16 + (y - 3)^2 - 9 - 15 = 0

(x + 4)^2 + (y - 3)^2 = 40

(-4 , 3) is the center of equation.:x^2 + y^2 + 8x - 6y - 15 = 0 .

(x + 4)^2 - 16 + (y - 3)^2 - 9 - 15 = 0

(x + 4)^2 + (y - 3)^2 = 40

(-4 , 3) is the center of equation.:x^2 + y^2 + 8x - 6y - 15 = 0 .

(3x - 1)^2 = 5

3x - 1 = ± sqrt 5

3x = 1 ± sqrt 5

x = (1 ± sqrt 5)/3

3x - 1 = ± sqrt 5

3x = 1 ± sqrt 5

x = (1 ± sqrt 5)/3

x^2 + 5x + 1 = 0

a = 1, b = 5, c = 1

discriminant = b^2 - 4ac = 25 - 4 = 21

x = (-5 ± sqrt 21)/2

a = 1, b = 5, c = 1

discriminant = b^2 - 4ac = 25 - 4 = 21

x = (-5 ± sqrt 21)/2

The distance between the points (5, -2) and (-7, 3) is 13 .

Let the distance is d

d^2 = (-7-5)^2 + {3 - (-2)}^2

d^2 = 144 + 25

d^2 = 169

d = 13

Let the distance is d

d^2 = (-7-5)^2 + {3 - (-2)}^2

d^2 = 144 + 25

d^2 = 169

d = 13

The solution set for (x + 2)(2x + 3) = 6 is {-7/2, 0}.

(x + 2)(2x + 3) = 6;

2x^2 +3x + 4x + 6 = 6;

2x^2 + 7x + 6 - 6 = 0;

2x^2 + 7x = 0;

x(2x + 7) = 0;

x = 0;

2x + 7 = 0; 2x = -7; x = -7/2

(x + 2)(2x + 3) = 6;

2x^2 +3x + 4x + 6 = 6;

2x^2 + 7x + 6 - 6 = 0;

2x^2 + 7x = 0;

x(2x + 7) = 0;

x = 0;

2x + 7 = 0; 2x = -7; x = -7/2
