Quadratic equations
Let’s recap first: Linear equations Usually only 1 unknown. Highest power is 1 Solve them by: If there are fractions find the LCD Multiply all terms on both sides of the equation by the LCD Simplify further by removing brackets Move all terms with variable to left of = sign by performing inverse operations Move … Read more
