What are the solutions of the equation: z^2 - 12z + 36 = 0?
a. -6, 6
b. 6, 6
c. 6, -6
d. -6, -6

Write a story that matches with the expression 42x-5 pls hurry

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

Someone me! if you’re smart you can solve this!
