Exercise 11 (D) | Q 5.1

Factorize x (x³ - y³ ) + 3xy ( x - y )

Factorize: `a^2 x^2 + (ax^2 + 1)x + a`

Multiply: x²+ 4y² + 2xy − 3x + 6y + 9 by x − 2y + 3

Divide: 9x² - 24xy + 16y² by 3x- 4y

Divide: 6x³ + 5x² − 21x + 10 by 3x − 2

The area of a rectangle is 6x² – 4xy – 10y² square unit and its length is 2x + 2y unit. Find its breadth.

Solve the following equation.

4(x + 12) = 8

A student wrote an algebraic expression for “5 less than a number n divided by 3” as `n/3 - 5`. What error did the student make?

Match Column I with Column II in the following:

Column I	Column II
1. The difference of 3 and a number squared	(a) 4 – 2x
2. 5 less than twice a number squared	(b) n² – 3
3. Five minus twice the square of a number	(c) 2n² – 5
4. Four minus a number multiplied by 2	(d) 5 – 2n²
5. Seven times the sum of a number and 1	(e) 3 – n²
6. A number squared plus 6	(f) 2(n + 6)
7. 2 times the sum of a number and 6	(g) 7(n + 1)
8. Three less than the square of a number	(h) n² + 6
