2x 2 - 2x - 1 = 0
**Weegy:** (2x - 1)(x + 5) = 0; 2x - 1 = 0; 2x = 0 + 1; 2x = 1; x = 1/2; x + 5 = 0; x = 0 - 5; x = -5; the solution set is (1/2, -5) **User:** x 2 + 5x + 4 = 0
**Weegy:** 2x - 1 **User:** 5x2 + 7x = 6 (More)

2x^2 - 2x - 1 = 0

a = 2, b = -2, c = -1

b^2 - 4ac = (-2)^2 - 4(2)(-1) = 4 + 8 = 12

x = [-b ± sqrt (b^2 - 4ac)]/2a

= (2 ± sqrt 12)/4

= (2 ± 2 sqrt 3)/4

= (1 ± sqrt 3)/2

a = 2, b = -2, c = -1

b^2 - 4ac = (-2)^2 - 4(2)(-1) = 4 + 8 = 12

x = [-b ± sqrt (b^2 - 4ac)]/2a

= (2 ± sqrt 12)/4

= (2 ± 2 sqrt 3)/4

= (1 ± sqrt 3)/2

x^2 + 5x + 4 = 0

(x + 1)(x + 4) = 0

x = -1 or x = -4

(x + 1)(x + 4) = 0

x = -1 or x = -4

(x + 3)(x + 4) = 5 is quadratic.

(x + 3)(x + 4) = 5

x^2 + 3x + 4x + 12 = 5

x^2 + 7x + 7 = 0

(x + 3)(x + 4) = 5

x^2 + 3x + 4x + 12 = 5

x^2 + 7x + 7 = 0

The line of symmetry of the parabola whose equation is y = ax^2 - 4x + 3 is x = -2. -1 is the value of "a".

4/2a = -2

4 = -4a

a = -1

4/2a = -2

4 = -4a

a = -1
