when we say 2a this means 2 * a and when we say a2, this means a * 2. so at the end of the day we will get same answers.

What is a2 math?
Students first study the AS (Advanced Subsidiary) course. Some will then go on to study the second part of the A Level course, called A2.This means that AS and A2 courses are designed so that difficulty steadily increases: AS Mathematics builds from GCSE Mathematics.
What is a2 b2 in algebra?
a2 + b2 = (a+b)2 – 2ab nd a2 – b2 = (a + b)(a – b)
What does b2 mean in algebra?
B1, b2 are the lengths of each base. h is the height (height) Remember that the bases are the two parallel sides of the trapezoid. The height (or height) of a trapezoid is the perpendicular distance between its two bases.
What is the formula a2 b2?
a2 – b2 = (a + b)(a – b ) .
Is A2 and 2a the same?
theres no difference. I could try to explain to you: when we say 2a this means 2 * a and when we say a2, this means a * 2. so at the end of the day we will get same answers.
What is the formula of a BC 2?
(a + b – c)2 formula is read as a plus b minus c whole square. Its expansion is expressed as (a + b – c)2 = a2 + b2 + c2 + 2(ab – bc – ca).
Is A² B² same as a B ²?
Both are completely different.
What is A +B 3?
The (a + b)^3 formula is used to find the cube of a binomial. the formula for the cube of the sum of two terms.

What is a4 b4?
Answer: a4 – b4 =( a2)^2 -( b2)^2. — Equation 1. This is similar to a2-b2 which results in (a-b)(a+b) but the only thing is here a and b became a2 and b2.
What is a2 2ab b2?
a2 + 2ab + b2 = (a + b)2. and. a2 – 2ab + b2 = (a – b)2. 2. To use: if the first and last terms of a trinomial are squares, try writing a perfect square; then use the square formula to see if you are correct.
What is the whole cube of a/b c?
The Formula is given below :
(a + b + c)³ = a³ + b³ + c³ + 3 (a +b) (b + c) (a+ c) Explanation : Let us just start with. (a+b+c)² = a² +b² + c²+2ab+2bc+2ca. =a² +b² + c²+2(ab+bc+ca)
What should be added to get 7/12 to get?

What does a B mean in maths?
We use to denote the universal set, which is all of the items which can appear in any set. This is usually represented by the outside rectangle on the venn diagram. A B represents the intersection of sets A and B. This is all the items which appear in set A and in set B. A B represents the union of sets A and B.
Is a 2 B 2 C 2 only for right triangles?
The Pythagorean theorem applies to right triangles. Recall that the Pythagorean Theorem states, for a right triangle with legs of length a and b and hypotenuse of length c, that a2+b2=c2. The hypotenuse is the side that is across from the right angle, and it is the longest side of the triangle.
Is a square B square C square?
The a2 + b2 + c2 formula is one of the important algebraic identities. It is read as a square plus b square plus c square.
How do you solve ABC 3?
- There are many expansions of this identity, some of them are given below:-
- (a+b+c)³=[(a+b)+c]³=(a+b)³+3(a+b)²c+3(a+b)c²+c³
- (a+b+c)³=(a³+3a²b+3ab²+b³)+3(a²+2ab+b²)c+3(a+b)c2+c³
- (a+b+c)³=a³+b³+c³+3a²b+3a²c+3ab²+3b²c+3ac²+3bc²+6abc.
- (a+b+c)³=(a³+b³+c³)+(3a²b+3a²c+3abc)+(3ab²+3b²c+3abc)+(3ac²+3bc²+3abc)−3abc.
