How many solutions are there for the equation? x2 + 16 = 8x

Question

anonymous · Answer

well since x^2, there can be a possibility of 2 solutions... but you would have to solve for x to make sure there are not repeated roots ;)

anonymous · Answer

if there are repeated roots then there is only 1 solution

campbell_st · Answer

there are always 2 solutions to a quadratic. 

In your question the solution is repeated.

anonymous · Answer

like are we talking about real solutions?

anonymous · Answer

so there is only 1?

anonymous · Answer

@GreenBeanDemphsey solve for x and see for yourself ;)

anonymous · Answer

can I use just any number that I choose?

campbell_st · Answer

it doesn't matter whether the solutions are real or complex. 

you will always have 2 solutions.... and in your questions the 2 solutions are identical, hence being called repeated solutions

anonymous · Answer

@GreenBeanDemphsey no, you cannot. you have to factor your quadratic equation to see which values for x satisfy the expression!

anonymous · Answer

the answer chooses are 
2
1
0

anonymous · Answer

yes, those are how MANY values for x satisfy the quadratic equation. not which values for X work...

anonymous · Answer

its asking how many answers are there for x not which one fits in x

anonymous · Answer

i know, you have to solve for x to see how many fit
