What is the quadratic equation?

Answer 1

x = -b +/- the square root of (b^2 - 4ac) / 2a

but it's easier to say it than type it

x equals the opposite of b plus or minus the square root of b squared minus 4ac, all over 2 times a

my eighth grade math teacher taught it to me in song to the tune of the Notre Dame fight song. it is forever in my head.

Answer 2

x= -b+or - sqrt(b^2-4ac) all over 2a


You should make all equations that you want to use the quadratic equation for look like this: +or -ax^2+or -bx+or - c

just plug in the values of all the variables. If you need more help try this site. Purple Math is an excellent algebra resource.

This is the quadratic formula.

a quadratic equation is really a polynomial that is raised to the second degree which means that it starts with a term that is squared

like: 2x^2-4x+22

Answer 3

The variable quantity is x and questions ask for values of x to be calculated.

a , b and c are constants.

A quadratic equation would then be shown as:-
ax² + bx + c = 0

5x² + 2x - 7 = 0 is an example chosen at random.

Answer 4

It's an equation which contains a variable raised to the second power.

Answer 5

an equation that its largest degree is two
the general formula for that is: ax^2+bx+c=0 where b and c can get zero value, but a cants

Answer 6

Quadric Equation

Standard form

ax² + bx + c = 0

- - - - - - - - - - - - -s-

Answer 7

-B+sq rt of (b^2-4AC) / 2A
-B-sq rt of (b^2-4AC)/ 2A
Is the quadratic formula

Answer 8

a2 + b2 = c2
