How do you find terms in x 3?

Starts here3:13Binomial theorem: finding the coefficient of x^3 in (2-4x)^5YouTubeStart of suggested clipEnd of suggested clip58 second suggested clipAnd that this gives me minus 2560 so therefore the term is minus 2 5 6 so X cubed. So theMoreAnd that this gives me minus 2560 so therefore the term is minus 2 5 6 so X cubed. So the coefficient is just minus 2 5 6. So to recap to get the X cubed term required. Minus 4 X to the power of 3.

What is 3rd term in binomial expansion?

The binomial theorem states the principle for expanding the algebraic expression (x + y)n and expresses it as a sum of the terms involving individual exponents of variables x and y. Therefore, the third term in the expansion of (a + b)n = C(n, 2)a2 – b(n – 2).

What is the coefficient of x 3 in the expansion of?

Coefficient of x3 in the expression (x−3)10 is −262440 .

How many terms does expansion of a b/c d 10 have?

Total number of terms is 66 B. Coefficient of abc is 90 Coefficient of a4b5c is 0 c.

What is the constant term in the expansion (x2 + 1 x)6?

The general term in the expansion of (x2 + 1 x)6 is: tr = (6 r). x12 − 3r The constant term, or x0 term, occurs when r = 4 and we find: t4 = 15 So the constant term is 15.

What is the X-2 term of X-6 and X-10?

So the x 6 term is 270 x 6 . So the x 10 term is 240 x 10 . So the constant term is 15 . So the x term is − 40 x . So the x − 2 term is 112. x − 2, which can also be written 112 x 2 . So the x 2 term is 4860 x 2 . So the x 33 term is 448 x 33 .

What is the x 33 term in math?

So the x term is − 40 x . So the x − 2 term is 112. x − 2, which can also be written 112 x 2 . So the x 2 term is 4860 x 2 . So the x 33 term is 448 x 33 . If playback doesn’t begin shortly, try restarting your device.
