For any positive integer n, the expansion of (x + y)n is C(n, 0)xn + C(n, 1)xn-1y + C(n, 2)xn-2y2 ++ C(n, n - 1)xyn-1 + C(n, n)yn. Each term r in the expansion of (x + y)n is given by C(n, r - 1)xn-(r-1)yr-1. Example: Write out the expansion of (x + y)7.

Writing Exponential Expressions in Expanded Form - YouTube YouTube Start of suggested clip End of suggested clip We take a look at this this is the quantity 5x cubed that means that we're going to have five xMoreWe take a look at this this is the quantity 5x cubed that means that we're going to have five x multiplied. Five times so if we were to expand this out. We would see five x times five x.

If a and b are real numbers and n is a positive integer, then (a + b)n =nC0 an + nC1 an ? 1 b1 + nC2 an ? 2 b2 +1. The total number of terms in the binomial expansion of (a + b)n is n + 1, i.e. one more than the exponent n.

For any positive integer n, the expansion of (x + y)n is C(n, 0)xn + C(n, 1)xn-1y + C(n, 2)xn-2y2 ++ C(n, n - 1)xyn-1 + C(n, n)yn. Each term r in the expansion of (x + y)n is given by C(n, r - 1)xn-(r-1)yr-1. Example: Write out the expansion of (x + y)7.

So if we split that firstMoreFirst example we're supposed to expand. X plus 4 multiplied by X plus 3. So if we split that first bracket into an X and a for each of those terms we'll multiply by that second bracket X plus 3.

Algebra expanding brackets - YouTube YouTube Start of suggested clip End of suggested clip So to expand these brackets you need to multiply. That. Four by everything inside the brackets.MoreSo to expand these brackets you need to multiply. That. Four by everything inside the brackets.

To expand three brackets, expand and simplify two of the brackets then multiply the resulting expression by the third bracket.

To expand a bracket means to multiply each term in the bracket by the expression outside the bracket. For example, in the expression 3 ( m + 7 ) , multiply both and 7 by 3, so: 3 ( m + 7 ) = 3 × m + 3 × 7 = 3 m + 21 .
