Q: What is the definition of algebra? A: Algebra is a branch of mathematics in which symbols, usually letters representing numbers or other mathematical elements, are used to represent unknown values and express general relationships that hold for any value of the unknown quantities.
-
Q: What is an example of an algebraic equation? A: An example of an algebraic equation is 3x + 7 = 10.
-
Q: What is the difference between an algebraic equation and an expression? A: An algebraic equation is a statement that two mathematical expressions are equal, while an expression is a combination of numbers, operations, and/or variables represented by a symbol.
-
Q: How do we solve algebraic equations? A: We solve algebraic equations by manipulating the equations in a variety of ways until the equation is complete and the unknown values can be determined.
-
Q: When solving linear equations, what type of systems can be used? A: Linear equations can be solved using a system of equations, including elimination, substitution, and graphing.
-
Q: What is the difference between linear equations and quadratic equations? A: Linear equations are equations in which the terms are in powers of one, and the graph of the equation is a straight line. Quadratic equations are equations in which the terms involve powers of two or higher, and the graph of the equation is a parabola.

Q: What is the ‘Quadratic Formula’? A: The Quadratic Formula is a formula used to solve quadratic equations. It is x = [-b +/- sqrt(b2 - 4ac)] / 2a.
-
Q: What is a factor in algebra? A: A factor in algebra is a quantity that divides an expression without leaving a remainder.
-
Q: What is the difference between a coefficient and a constant in algebra? A: Coefficients are numbers that are multiplied by variables, while constants are numbers that are added or subtracted in an expression.
-
Q: What is the ‘Distributive Property’ in algebra? A: The Distributive Property is a property of mathematics that states that multiplying a number by a sum is the same as multiplying each addend of the sum by the number and then adding them together.
