I have alot of question
1)2x^2-5x+67=0
2)7k^2-16k+100=0
3)10p^2+4p+77=0
4)3x^2=-4+8x
===================
You didn't ask any questions. You posted 4 equations.
1)2x^2-5x+67=0
If you want to solve for x:
Solved by pluggable solver: SOLVE quadratic equation (work shown, graph etc)
Quadratic equation (in our case ) has the following solutons:



For these solutions to exist, the discriminant should not be a negative number.

First, we need to compute the discriminant : .

The discriminant -511 is less than zero. That means that there are no solutions among real numbers.

If you are a student of advanced school algebra and are aware about imaginary numbers, read on.


In the field of imaginary numbers, the square root of -511 is + or - .

The solution is , or
Here's your graph:

==================
Do the others the same way.
