Find the Square of : 3a - 4b - Mathematics

Find the square of : 3a - 4b

Sum

We know that
( a - b )² = a² + b² - 2ab
( 3a - 4b )² = 9a² + 16b² - 2 x 3a x 4b
= 9a² + 16b² - 24ab

Write the following cube in expanded form:

`[3/2x+1]^3`

Factorise the following:

8a³ – b³ – 12a²b + 6ab²

if `x + 1/x = 11`, find the value of `x^2 + 1/x^2`

Evaluate of the following:

`(10.4)^3`

Find the following product:

(4x − 5y) (16x² + 20xy + 25y²)

If x + \[\frac{1}{x}\] = then find the value of \[x^2 + \frac{1}{x^2}\].

(a − b)³ + (b − c)³ + (c − a)³ =

Find the squares of the following:
(2a + 3b - 4c)

Simplify:
(4x + 5y)² + (4x - 5y)²

Multiply x² + 4y² + z² + 2xy + xz – 2yz by (–z + x – 2y).
