If the first and last terms are perfect squares, and the middle term's coefficient is twice the product of the square roots of the first and last terms, then the expression is a perfect square trinomial. It is the coefficient of the x k term in the polynomial expansion of the binomial power (1 + x) n, and is given by the formula =!! First, to use synthetic division, the divisor must be of the first degree and must have the form x a If it divides evenly, we have in effect partially factored the polynomial We maintain a great deal of good reference material on subjects ranging from college mathematics to formulas The degree function calculates online the degree of a . y 2 + + nC n y n. General Term = T r+1 = nCr x n-r . Voiceover:So we've got 3 Y squared plus 6 X to the third and we're raising this whole to the fifth power and we could clearly use a binomial theorem or pascal's triangle in order to find the expansion of that. for this question I tried to use binomial theorem to find a specific term. To get any term in the triangle, you find the sum of the two numbers above it. Binomial coefficient is an integer that appears in the binomial expansion. {\left (x+2y\right)}^ {16} (x+ 2y)16. can be a lengthy process.
