Are you lost in translation when it comes to translating a graphed object? This free video lesson will explain it in simple terms and make translations into child’s play.
When simplifying problems that have reciprocal trig functions, start by substituting in the identities for each. If possible, write tangent in terms of sine and cosine.
To solve a quadratic equation by factoring, you set one side of the equation equal to zero and use the zero product property to factor the equation.
A percentage is a special ratio in which the second term of the ratio is always 100. By expressing a number as a percentage you are reflecting how many times it occurs in relation to 100 times.
Learning to work with ratios and proportions is one of the most useful things you can learn to do.
It is important to combine like terms so that you are dealing with the simplest form of the expression or equation.
The standard form of a line puts the x and y terms on the left hand side of the equation, makes the coefficient of the x-term positive, and puts everything else on the right side.
Solving quadratic equations using square roots works best under special circumstances. If your equation does not have a “b” term this technique may be a good one for you to try.
When we solve quadratic equations by factoring we set one side of the equation to zero, and then factor the quadratic equation, so we can use the zero product property to determine where x = 0.
Systems of equations are concepts that first show up in Algebra I. Systems of equations are problems with two or more equations that contain the same variables. There are four methods to solving systems of equations: graphing, substitution, elimination and matrices.
The properties of real numbers include the Associative, Commutative, Multiplicative and Additive Identity, Multiplicative and Additive Inverse, and Distributive Properties.
An important introduction to solving algebraic equations is learning how to handle single step equations.
The basics of multiplying polynomials is mastered when you learn the FOIL method. FOIL stands for First – Outside – Inside – Last. Watch our video lesson to master this Algebra technique.
