What is the secret to algebra?
Basic Points in Algebra Remember the basic rule: the higher the figure, the further it is from zero. Make long problems easier by having them organized. Put down every new stage on a new line. Learn variables which cannot be defined as numbers (x, y, and z).
What is simple algebra?
What Is Basic Algebra? Basic algebra is the field of mathematics that it one step more abstract than arithmetic. Remember that arithmetic is the manipulation of numbers through basic math functions. Algebra introduces a variable, which stands for an unknown number or can be substituted for an entire group of numbers.
What is the formula of a2 b2?
(A²-B²) = (A-B)² + 2AB.
What is a³ B³?
a³+b³=(a+b)(a²-ab+b²) a³-b³=(a-b)(a²+ab+b²) hope this help you.
What is a2 +b2?
a2+b2 : as, (a+b)2 = a2 +b2 + 2ab. so, a2+b2=(a+b)2 – 2ab. hence, proved. dome7w and 4 more users found this answer helpful.
Is a 3 b 3 a polynomial?
A polynomial in the form a 3 + b 3 is called a sum of cubes. A polynomial in the form a 3 – b 3 is called a difference of cubes.
What is B in algebra?
In the equation of a straight line (when the equation is written as “y = mx + b”), the slope is the number “m” that is multiplied on the x, and “b” is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the “slope-intercept form”.
Is a B 2 a binomial?
BIG IDEA The square of a binomial a + b is the expression (a + b)2 and can be found by multiplying a + b by a + b as you would multiply any polynomials.
What is the square of a B?
The square of this expression is written as ( a − b ) 2 in mathematical form and it is expanded as a 2 − 2 a b + b 2 mathematically. In mathematics, this algebraic identity is used as a formula and it is called in the following three ways. The square of difference of the terms formula.
What is foil algebra?
“A technique for distributing two binomials. The letters FOIL stand for First, Outer, Inner, Last. First means multiply the terms which occur first in each binomial. Then Outer means multiply the outermost terms in the product.”
What does foil stand for in English?

What is the foil method used for?
The FOIL method is a technique used to help remember the steps required to multiply two binomials. Remember that when you multiply two terms together you must multiply the coefficient (numbers) and add the exponents.
What does the F in foil mean?
first
What is the reverse foil method?
“Reverse FOIL” is a method of factoring a quadratic trinomial by trial-and-error. The strategy is to determine the First and Last terms of each binomial in the factored product so the Outer and Inner products add to the middle term.
What does Trinomial mean?
(Entry 1 of 2) 1 : a polynomial of three terms. 2 : a biological taxonomic name of three terms of which the first designates the genus, the second the species, and the third the subspecies or variety.
How do u do foil?
FOIL stands for First, Outer, Inner, Last. Multiply binomials by first multiplying the first terms of both, then the two outer terms, then the two inner terms, and then the last terms of both. Then, add everything together!
