What is the formula of a BC ²?

=a²+b²+c²+2ab+2bc+2ac.

What is ABCD formula?

Answer: (a – b – c)2 = a2 + b2 + c2 – 2ab + 2bc – 2ca.

What is the formula a/b 2?

The (a – b)2 formula is used to find the square of a binomial. This (a – b)2 formula is one of the algebraic identities. This formula is also known as the formula for the square of the difference of two terms. The (a – b)2 formula is used to factorize some special types of trinomials.

What are the factors of a 2 AB BC CA?

Therefore, the factors of a2 + ab +bc + ca are ( a + b ) ( a + c ).

What is the value of AB BC CA?

Therefore [a-b b-c c-a] is equal to \[0\]. Hence, the correct answer is option A. Note: [a-b b-c c-a] is the scalar triple product of thee three vectors which are a-b, b-c and c-a and the absolute value of [a-b b-c c-a] is equal to the volume of a parallelepiped spanned by the vectors a-b, b-c and c-a.

What are the properties of the binomial expansion (A + B)N?

Properties of the Binomial Expansion (a + b)n. There are n+1 terms. The first term is an and the final term is bn. Progressing from the first term to the last, the exponent of a decreases by 1 from term to term while the exponent of b increases by 1. In addition, the sum of the exponents of a and b in each term is n. If…

What is the complete expansion of a3b5?

For, the coefficient of a3b5 is equal to the coefficient of a5b3, which is 56. And so on for the remaining coefficients. Here is the complete expansion: 28 a2b6 + 8 ab7 + b8. Example 6.

What is the total number of terms in the expansion (x+y) n?

The total number of terms in the expansion of (x+y) n are (n+1) The sum of exponents of x and y is always n. nC 0, nC 1, nC 2, ….., nC n are called binomial coefficients and also represented by C 0, C 1, C 2, ….., C n

How do you find the coefficient of expansion with like terms?

In general, for the expansion of (x + y)n on the right side in the n th row (numbered so that the top row is the 0th row): after combining like terms, there are n + 1 terms, and their coefficients sum to 2n. .
