are you copy pasting all of your homework?

anonymous · Answer

no just the ones i dont know

anonymous · Answer

what is an quadratic equation?

anonymous · Answer

@shahzadjalbani: Please don't give away answer. This is against our code of conduct. Thanks

anonymous · Answer

Ok

anonymous · Answer

Alrght, coming back to the question. Any polynomial of order 2 is a quadratic equation.

anonymous · Answer

Quadratic Equation
Ax2 + Bx + C = 0

anonymous · Answer

formula^?

anonymous · Answer

Right, so is this quadratic:

$x^3 - 6x^2 + 8 = 0 $

anonymous · Answer

@tylertriebs nOW SELECT the equations having this order

anonymous · Answer

the 2nd,4th,and last

anonymous · Answer

yes

anonymous · Answer

No.

anonymous · Answer

y

anonymous · Answer

It has a $ x^3$ term

anonymous · Answer

Quadratic equation is one whose greatest degree of a variable is 2 Like x2+2x+1

anonymous · Answer

oh i get so the first # has to squared @FoolForMath

anonymous · Answer

Yes

anonymous · Answer

Now determine which are the quadratic equations.

anonymous · Answer

and it should be the order of that polynomial.

anonymous · Answer

ok so then it would be the 1st 4th and last

anonymous · Answer

Note: $Ax+bx^2+c$ is also quadratic.

anonymous · Answer

Yes @tylertriebs  Now you are right.

anonymous · Answer

ok

anonymous · Answer

ok i got it thanks guys

anonymous · Answer

a quadratic equation is also a perabula right

anonymous · Answer

Yes and it's graph is lik
