**CBSE Class 8 Mathematics/Factorisation – Chapter 14Extra Questions for Practice/Model QuestionsFill in the blanks:**

**——— is a factor of every term.****The common factor of 2x and y are ———–****The factorisation of 5x – 25 is —————-****The factors of y(y +z) + 9(y +z) are ———–****The value of 2x -6 at x = 5 is —————**

Answer the following:**Factorise:**

a) 12x + 36

b) 22y – 33z**Factorise 6xy – 4y + 6 – 9x****Factorise x (2+y) + (8 + 4y)****Factorise (xy +x) + y + 1****Find and correct the errors in the following statements:**

a) 2(x -6) = 2x – 6

b) 3x + 2y = 5xy

**ANSWERS:**

**1****1****5(x – 5)****(y + z) (y + 9)****4****a) 12x + 36 = 12(x + 3)**

b) 22y – 33z = 11(2y – 3z)**6xy – 4y + 6 – 9x = 2y (3x – 2) – 3(3x – 2) = (3x – 2) (2y – 3)****x (2 + y) + (8 + 4y) = x (2 + y) + 4( 2 + y) = (2 + y) (x + 4)****(xy + x) + y + 1 = x(y + 1) + y + 1 = (y + 1) (x + 1)****a) 2 (x – 6) = 2x – 12**

b) 3x + 2y itself. We can’t add these two terms because the variables are different.
