A B C D 3 Formula
A 3 b 3 c 3 d 3.
A b c d 3 formula. Microsoft excel is compatible with devices including windows mac apple and androids. The graph of any quadratic function has the same general shape which is called a parabola. The roots of the quadratic equationax2 bx c 0 a6 0 are b p b2 4ac 2a the solution set of the equation is b p 2a b p 2a where discriminant b2 4ac 32. The function f x ax 2 bx c is a quadratic function.
If a ib x iy wherei p 1 then a xand b y 31. How would my solution look in the quadratic formula. It was released on september 30 1985 and is the most used spreadsheet program. Suppose you have ax 2 bx c y and you are told to plug zero in for y.
If a ib 0 wherei p 1 then a b 0 30. Using a 1 b 3 and c 4 my solution looks like this. Considering the cubes of a we can choose 3 a s from 3 factors in one way only. The location and size of the parabola and how it opens depend on the values of a b and c.
The sum of the coefficients is 4. Considering a 2 we can choose 2 a s from 3 factors in c 3 2 3 ways. Similarly for the other letters. A b 2 a 2 2ab b 2 a b c d ac ad bc bd a 2 b 2 a b a b difference of squares a 3 b 3 a b a 2 ab b 2 sum and difference of cubes x 2 a b x ab x a x b if ax 2 bx c 0 then x b b 2 4ac 2a quadratic formula.
Then as expected the solution is x 4 x 1. This formula would be used in microsoft excel which is a spreadsheet program.
