"WebAn equation is a statement that two expressions are equal. For example, the expression 5 + 3 5 +3 is equal to the expression 6 + 2 6 +2 (because they both equal 8 8 ), so we can write the following equation: 5 + 3 = 6 + 2 5 + 3 = 6 + 2. All equations have an equal sign ( = = ). The = = sign is not an operator like addition ( + +) or subtraction ... " - Sichart equation

WebAboutTranscript. The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations. WebThe quadratic formula helps you solve quadratic equations, and is probably one of the top five formulas in math.
