4x^2-8x+7-0 =0

Christ, use parenthesis, faggot.

/thread

op is fag

X=2+-√4-7/4

√1.75 = 1.5
X= 2+- 1.5
First X: 3.5
Second X: 0.5

(4x^2-8x+7-0)-(4x^2-8x+7-0)
There you go

Both these are wrong

There are no real zeroes you dip
Determinant= 64-112=-48
Also, learn your quadratic formula

fucking kill yourself you cancerous piece of shieeeet

user is right.

If it's solving equations you must make the left side equal the right.
Also if there is polynomials involved you can only add,subtract,multiply and divide like terms.
So 4x^2 stays 4x^2. You just have to subtract both sides by that like term.

4x^2-8x+7(-0)

Two solutions:

x =(8-√176)/8=1-1/2√ 11 = -0.658
x =(8+√176)/8=1+1/2√ 11 = 2.658

Second grade equiation with complex numbers

Wait what
You can use det with basic linear equations? Any name for this shit?
I want to look it up.

as it stand that isnt an equation, it's literal a bunch of terms. You uneducated fuck.

I cannot do math like this. It makes no sense to me anymore. Are the anons in this thread students or are you guys actually applying this math to something? I forgot this shit as soon as I graduated high school (2006)

the answer is 0

I've always enjoyed learn I ngnoutside of school so I kept learning about Math and Sciences after school. That helps me remember the stuff I learned from school.

learning outside*

what the fuck is the ppint of -0? you arent subtracting anything?

Too bad they didn't teach English from that school
