Question and answer
Use the discriminant and select whether the roots of 5x 2 - 4x + 3 = 0 are real or non-real. real non-real
5x^2 - 4x + 3 = 0 a = 5, b = -4, c = 3 b^2 - 4ac = (-4)^2 - 4(5)(3) = 16 - 60 = -44 < 0 the roots are non-real.

5x^2 - 4x + 3 = 0
a = 5, b = -4, c = 3
b^2 - 4ac = (-4)^2 - 4(5)(3) = 16 - 60 = -44 < 0
the roots are non-real.

Find the center of the following equation. x 2 + y 2 + 8 x - 6 y - 15 = 0
Question
Updated 11/10/2014 11:24:59 PM
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 .

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

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
