Create a quadratic equation that has complex solutions

Mathematics
1 answer:
svetoff [14.1K]3 years ago
4 0

Answer:

x^2 + x + 2 = 0.

Step-by-step explanation:

The discriminant b^2 - 4ac is < 0 for complex roots.

So we can choose appropriate values for a, b and c.

Let b = 1,  a = 1 and  c = 2 so b^2 - 4ac = 1 - 4*1*2 = -7.

So our equation is:

x^2 + x + 2 = 0.

Plot the x-intercept(s), y-intercept, vertex, and axis of symmetry for the function below.
telo118 [61]
<span>g(x) = x^2 + 4x + 3

y-intercept:  let x=0.  Then y=3.  y-intercept is (0,3).

roots:  set g(x) = 0 and solve for x.  x=-1 and x=-3.

                                                                                       -4
axis of symmetry:  find x = -b / (2a), which here is x = ----- = -2
                                                                                        2</span>

Factor 5a^2-30a+45, and 2x^5+x^4-2x-1.
Mrrafil [7]

Step-by-step explanation:

{5a}^{2}  - 30a + 45

5( {a}^{2}  - 6a + 9)

5(a-3)(a-3)

5(a-3)^2

{2x}^{5}  +  {x}^{4}  - 2x - 1

X^4(2x+1) - (2x+1)

(x^4-1)(2x+1)

(x^2-1)(x^2+1)(2x+1)

(x-1)(x-1)(x^2+1)(2x+1)
