Question:Please can someone inform me on WHAT the Quadratic Formula actually is, a definition of it, an example of it, and how to solve it.
Please and thanks you.
Answers:the quadratic formula solves for x in a formula of the form ax^2+bx+c=0 an example would be x^2+8x+16 the formula is negative b plus or minus the square root of (b^24ac) all divided by 2a 8+square root of (6464) = 8 then divide by 2a 8square root of (6464) = 8 then divide by 2a a=1 so 2a=2 8/2= 4 therefore in x^2+8x+16=0, x=4

Question:hi, hope someone can help
A quadratic equation is of the form ax^2 + bx + c = 0
does this mean that ax has to have a power
Also are there only three types of equation (being linear, quadratic and simultaneous) Thanks for any help
Answers:Yea, in a quad. eq. ax has to have a power of 2. If there is no power it becomes a linear equation. If there is more than power of 2, it is not quadratic anymore. TW K

please and thank you!!! You guys are awesome!!!!
Answers:quadratic equation: of the form ax^2 + bx + c = y. The graph is a parabola. Any archway is an example of a parabola. Look at the underside of a bridge for example. Concave up: the graph opens upwards (similar to the letter U). Concave down: the graph opens downwards (like the arch under a bridge). Linear functions are straight lines. y = mx + b where m is the slope (or amount of "slant") of the line and b is the yintercept (where the graph crosses the yaxis).

Question:how would u use it in this situation?
Write a quadratic function of the form y=a(x  h)^2 +k for the parabola with vertex (2,3) and a =  4
Answers:You have what you need: y=4(x3) +2 If you plot it you'll see that it has two zeros. A polynomial of degree 2 will have two zeros. If you actually multiply you'll get: 4x +24x34. Here you will see that the max exponent in x is 2 which means it's quadratic.

Quadratic Rap :Title says all, a rap about quadratics :] haha. This is an old video, hella youngg! haha. well not really xP. maybe backk in january/february, but still different. Don't hate cause we're just messing around for an A x] Lyrics (dont be shy to sing along!): [ORIGIN] QUADRATIC do you know what that means? it's a quadratic, quad meaning four quad like quadrant graph quad one two three four QUADRATIC do you know what that means? originating from the word quadrate meaning to make a square making all four corners or else it'll be bare also for the equation ax2 + bx + c ax2 is a necessity (DEFINITION PLEASE) [DEFINITION] QUADRATIC do you know what that means? it's a type of equation, in standard equals zero all us abc legit, real, nonimaginary not like the fake coach bags your friends would carry oops did i just say that? i mean its all got a price, we dont equal zero, and we're cool like ice (APPLICATION!) [APPLICATION] QUADRATIC do you know what that means? the equation, what's it reppin'? yknow, the sign, figure, the logo your makin' is it the movement of a rainbow? a grin or smile? a frown when your down when you get dominated after many trials? no matter what or no matter where it all makes a curved ax2 [ax2:] aye yo, wsup im ax2 when you got the little '2' its been declared that the linear line turns parabolic oh dang, i juss cant stop like a systolic you see when i smile, things go up arrows keep going and it'll never stop but you see when im negative you juss cant go and ...
