Question

How do u do quadratic equations i dont get it?

Answer 1

for example: -3xsquared+75=0

Answer 2

That one is one you can probably solve like a regular equation:
-3x^2=-75
x^2=-75/-3=25
square root both sides and x=5

Answer 3

There are other methods for solving more complicated quadratic equations such as factoring and the quadratic formula.

Answer 4

how do u do that?

Answer 5

Quadratic equations come in this format: ax^2+bx+c

If you want to use the quadratic formula it's x\[(-b \pm \sqrt{b^2-4ac})/2a\]

If you want to factor you can sometimes divide by a GCF. Often you have to put it in this format: (x+k)(x+m).
m & k have to be 2 number such that, when you multiply them together you get c, and when you add them together you get b.
