Help?

1. ) 2x2 – 8x + 4 = 0
2.) 2x2 – 8x + 10 = 0

Solve for X. Anyone out there can help me?

 

[Dr.Peterson]

You can start in each case by dividing the entire equation by 2.

Then please show us your work, so we can know what specific help you need!

In particular, if you are having trouble factoring, that is not your fault! These need to be solved by another method. What methods do you know?

 

[Steven G]

I assume you mean 2x^2 - 8x + 4 = 0 and 2x^2 - 8x + 10 = 0.

What is in bold are the same for any value for x; 2x^2 - 8x + 4 = 0 and 2x^2 - 8x + 10 = 0

How can you add 4 and 10 to the same value and exact to get equality? What do you think the answer should be?

 

[Dr.Peterson]

I am presuming these are two separate problems, not a system of equations.

@Tara Marie, another important piece of context I'd have wanted from you is whether you have learned about complex numbers as solutions to equations.

@Tara Marie

We really like you to show your work so we know where even to start to help you.

Have you been taught the quadratic formula? Have you been taught about the discriminant of a quadratic equation? Have you heard those words?

… and exact to get equality …

Jomo meant to type 'expect to get'.

Oh, I thought Jomo was buying his booze from my moonshiner!

You've been drinking for that long?!
