WebI think this is normally part of a linear algebra class, where we learn to work with vectors and matrices. Here are a few useful facts that you can understand right now: if x is a column vector, then x T x = ‖ x ‖ 2. If x and y are column vectors, then their dot product x, y is equal to x T y. Finally, we can use FOIL with column vectors ... Web2 days ago · All steps. Final answer. Step 1/3. The answer provided below has been developed in a clear step by step manner ⇒.

WebApr 9, 2024 · Expand the first two brackets: (x −y)(x − y) = x2 −xy −xy + y2. ⇒ x2 +y2 − 2xy. Multiply the result by the last two brackets: (x2 + y2 −2xy)(x − y) = x3 − x2y + xy2 − y3 −2x2y + 2xy2. ⇒ x3 −y3 − 3x2y + 3xy2. … WebAlgebra. Expand Using the Binomial Theorem (x+y+z)^3.

WebSep 13, 2024 · Using this , the expansion you get for $(x=y)^4$ is : $$(x + y)^n = x^4 + 4x^3y+6x^2y^2+4xy^3+y^4$$ This is the same result you get when you do it algebraically as well. Share WebAboutTranscript. The Binomial theorem tells us how to expand expressions of the form (a+b)ⁿ, for example, (x+y)⁷. The larger the power is, the harder it is to expand expressions like this directly. But with the Binomial theorem, the process is … WebMay 9, 2024 · When we expand \({(x+y)}^n\) by multiplying, the result is called a binomial expansion, and it includes binomial coefficients. If we wanted to expand \({(x+y)}^{52}\), we might multiply \((x+y)\) by itself fifty-two times. This could take hours!
