Find the value of the discriminant describe the number and type of roots for the equation. Then find the exact solution of the following quadratic equation by using the Quadratic Formula.
x2 - 6x + 25 = 0
a.
The discriminant is -64, so there are 2 complex roots.
x = 1103-05-05-00-00_v2_files/i0050000.jpg
c.
The discriminant is 34, so there are 2 real and rational roots.
x = 1103-05-05-00-00_v2_files/i0050001.jpg
b.
The discriminant is -64, so there are 2 complex roots
x = 1103-05-05-00-00_v2_files/i0050002.jpg
d.
The discriminant is -34, so there are 2 complex roots
x = 1103-05-05-00-00_v2_files/i0050003.jpg

hello : x² - 6x + 25 = 0 The discriminant is : b²-4ac a =1 b = - 6 c =25 (-6)²-4(1)(25) =36-100 = -64 The discriminant is -64, so there are 2 complex roots
