Basic Algebra Formulas вђ Syft Square of the sum: (a b)2 = a2 2ab b2. square of the difference: (a– b)2 = a2– 2ab b2. difference of squares: a2–b2 = (a b)(a– b) this quick example of the square of the sum formula, will help you see how this formula works in practice. the following formulas are useful when expanding and simplifying binomials. Algebra is a branch of mathematics that substitutes letters for numbers. an algebraic equation depicts a scale, what is done on one side of the scale with a number is also done to either side of the scale. the numbers are constants. algebra also includes real numbers, complex numbers, matrices, vectors and much more.

Basic Algebra Formulas вђ Syft Example 1.4.12: calculate the simple interest earned on a 2 year investment of $1, 250 at an annual interest rate of 3 3 4. solution. convert 3 3 4 to a decimal number before using it in the formula. r = 33 4% = 3.75% = 0.0375. use this and the fact that p = $1, 250 and t = 2 years to calculate the simple interest. An expression consisting of 4 main parts, variables, operators, exponents, coefficients and constants along with an equal to symbol is known as an algebraic equation. let us take an equation, ax 2 bx c = d. in algebra, the term with highest exponent is written in the starting and further the terms are written with reducing powers. Moomoo math & science. moomoomath provides free video lessons, tips, and resources in pre algebra, algebra, algebra 2, and geometry along with a summary of each video lesson. under each summary is a practice link that takes teachers, parents, and students to free, interactive websites that reinforce each concept. When two binomials differ only by the sign between their terms (one a plus, the other a minus), we call this a difference of two squares. the rule is very easy to remember: subtract the square of the second term from the square of the first term. take a look:.
