What are the solutions to the equation over the complex numbers?

x2+75=0

enter your answers, as exact values, in the boxes.

  -5√3 i,   5√3 i.

Step-by-step explanation:

x^2 + 75 = 0

x^2 = -75

x = +/- √-75

= +/- √75 i

=  +/- 5√3 i.

25/4

step-by-step explanation:

call segment cd's length x. because dc and ab are parallel, angle acd and cab, so triangles adc and abc are similar and we can set up the equation x / ac = ac / ab, or x / 5 = 5 / 4 and x = 25/4.

the probability is 0
