In elementary algebra, the binomial theorem (or binomial expansion) describes the algebraic expansion of powers of a binomialAccording to the theorem, it is possible to expand the polynomial (x y) n into a sum involving terms of the form ax b y c, where the exponents b and c are nonnegative integers with b c = n, and the coefficient a of each term is a specific positiveY=2x2 Swap sides so that all variable terms are on the left hand side 2x2=y Subtract 2 from both sides 2x=y2 Divide both sides by 2 \frac{2x}{2}=\frac{y2}{2} Dividing by 2 undoes the multiplication by 2 x=\frac{y2}{2} sin (x – y) = sin x cos y – cos x sin y sin (60° – 30°) = sin 60° cos 30° – cos 60° sin 30° sin (30°) = (√3/2) × (√3/2) (1/2) × (1/2) 1/2 = 3/4 – 1/4 1/2 = 2/4 1/2 = 1/2 Hence verified cos (x y) = cos x cos y – sin x sin y cos (60° 30°) = cos 60° cos 30° – sin 60° sin 30°

Introduction x y is a binomial in which x and y are two terms In mathematics, the cube of sum of two terms is expressed as the cube of binomial x y It is read as x plus y whole cube It is mainly used in mathematics as a formula for expanding cube of sum of any two terms in their terms ( x y) 3 = x 3 y 3 3 x 2 y 3 x y 2 If you want to factor expressions of the form $\alpha x^2\beta xy\gamma y^2$, observe that $$\begin{align*}\alpha x^2\beta xy\gamma y^2&=\alpha y^2\left((xy^{1The same coefficient also occurs (if k ≤ n) in the binomial formula ( x y ) n = ∑ k = 0 n ( n k ) x n − k y k {\displaystyle (xy)^ {n}=\sum _ {k=0}^ {n} {\binom {n} {k}}x^ {nk}y^ {k}} (∗) (valid for any elements x, y of a commutative ring ), which explains the name "binomial coefficient"
