Question

The roots of the equation x^2-10x+25=0 are A: 2 imaginary roots. B: 2 real roots. C: 1 real root. D: there is no solution

Answer 1

Graph the equation to figure it out. Here is a hint: you can not factor this to get the answer.

Answer 2

It touches the x axis and that is a root. Even if it does not intersect.

Answer 3

It has one real root i.e U can factorise it like this (x-5)2 so make it equals to 0 and the solution is one i.e x=5 meaning the graph touches the x-axis only once

Answer 4

Thank you guys soo much for your help! I understand completely now! Much appreciated!
