How do you graph slope on a graphing calculator?
On all of the graphing calculators, they have the graphing things on it. First to make a graph, you need an equation. when you have the equation ready, you just press the button on the top left (for the most calculaters), the "y=" button. Then you will get a lot of empty lines for you to put the equations on. After you type all the equations, you will have to press the "graph button on the top right. then you will get a graph.
How do you solve equations with brackets?
Follow PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction), but do what is in the brackets first.
Who was the first person to use algebra?
Algebra was first used in 1800 BC. There is evidence of the solution for quadratic elliptic equations in the Strasburg Tablet from Old Babylon.
Can all quadratic equations be solved?
Well, that depends on what you mean "solve by factoring." For any quadratic equation, it is possible to factor the quadratic, and then the roots can be recovered from the factors. So in the very weak sense that every quadratic can be solved by a method that involves getting the factors and recovering the roots from them, all quadratic equations can be solved by factoring. However, in most cases, the only way of factoring the quadratic in the first place is to first find out what its roots are, and then use the roots to factor the quadratic (any quadratic polynomial can be factored as k(x - r)(x - s), where k is the leading coefficient of the polynomial and r and s are its two roots), in which case trying to recover the roots from the factors is redundant (since you had to know what the roots were to get the factors in the first place). So to really count as solving by factoring, it makes sense to require that the solution method obtains the factors by means that _don't_ require already knowing the roots of the polynomial. And in this sense, most quadratic equations are not solvable through factoring.
