Divide: - 50 + 40p by 10p

Sum

- 50 + 40p by 10p

`= (- 50 + 40"p")/(10"p") = (- 50)/"10 p" + "40 p"/"10 p"`

`= - 5/"p" + 4`

Factorize x³ - 2x² y + 3xy² - 6y³

125 + 8x³ - 27 y³ + 90xy

If \[x^2 + \frac{1}{x^2} = 18,\] find the values of \[x + \frac{1}{x} \text { and } x - \frac{1}{x} .\]

Multiply: x² + 4y² + z³ + 2xy + xz − 2yz by x − 2y − z

(x + y)³ − (x − y)³ can be factorized as

Divide: 6x² + 5x - 6 by 2x + 3

The area of a rectangular field is 25x2 + 20xy + 3y2 square unit. If its length is 5x + 3y unit, find its breadth, Hence find its perimeter.

Express the following as an algebraic expression:

Sum of p and 2r – s minus sum of a and 3n + 4x.

If x = 2 and y = 3, then find the value of the following expressions
