Question

Write the quadratic equation in standard form that has roots 4,-6 PLEASE HELP!!

Answer 1

Do you know what the standard form of a quadratic equation looks like?

Answer 2

And second of all do you know what the roots mean?

Answer 3

Nope

Answer 4

You would start by multiplying
(x -4) (x +6)
seems you might need a little more help than that.

Answer 5

So, x^2+2x-24

Answer 6

I multiplied it and got
x² +2x -24

Looks as if we agree

Answer 7

Also, how do you know where to put the + and -

Answer 8

So, x^2+2x-24

Answer 9

You just multiplied that and you want to know about where to put + and - ?

Answer 10

No i mean to get (x-4)(x+6), how do you know the its (x-4)?

Answer 11

Okay when you factor the equation down to
(x -4) (x +6) the full equation is actually
(x -4) (x +6) = 0
So in order for the equation to equal zero, x must equal 4 and x must equal -6.
