Test: Factorisation- 1 - Question 1

Factorise: 4y−12y + 9

Detailed Solution for Test: Factorisation- 1 - Question 1

We have 4y- 12y+9. comparing the equation with (a-b)2=a2-2ab+b2,gives us a2=(2y)2,2ab=2*3*2y and b2=(3)2.Hence the answer is (2y-3)2.

Test: Factorisation- 1 - Question 2

Divide as directed: 20 (y+ 4) (y2+ 5y+ 3) ÷ 5(y+ 4)

Detailed Solution for Test: Factorisation- 1 - Question 2

Test: Factorisation- 1 - Question 3

Factorise: 10x− 18x+ 14x4

Detailed Solution for Test: Factorisation- 1 - Question 3

10x2 − 18x3 + 14x= 2x(5x− 9x2 + 7x3) = 2x2(5− 9x + 7x2)

Test: Factorisation- 1 - Question 4

Divide the given polynomial by the given monominal: 8 (x3y2z2 + x2y3z2 + x2y2z3) ÷ 4x2y2z2

Detailed Solution for Test: Factorisation- 1 - Question 4

8 (x3y2z2 + x2y3z2 + x2y2z3) ÷ 4x2y2z2 

Test: Factorisation- 1 - Question 5

Factorise: x2+xy+ 8x+ 8y

Detailed Solution for Test: Factorisation- 1 - Question 5

x^2 + xy + 8x + 8y = x[x + y] + 8[x + y]

 = (x + y)(x + 8)

Test: Factorisation- 1 - Question 6

Solve: 7x2y2z÷ 14xyz

Detailed Solution for Test: Factorisation- 1 - Question 6

7x²y²z²÷14xyz
=(7/14)(x²/x)(y²/y)(z²/z)
=1/2(x)(y)(z)
=1/2xyz.

Test: Factorisation- 1 - Question 7

Divide as directed: 26xy (x + 5) (y – 4) ÷ 13x (y – 4)

Detailed Solution for Test: Factorisation- 1 - Question 7

26xy(x + 5) (y - 4) / 13x(y - 4)
Cancelling 13x(y-4)
=2y(x+5)

Test: Factorisation- 1 - Question 8

Divide the given polynomial by the given monomial: (x3+ 2x2+ 3x) ÷ 2x

Detailed Solution for Test: Factorisation- 1 - Question 8

(x3+2x2+3x)/2x
=x(x2+2x+3)/2x
=(x2+2x+3)/2

Test: Factorisation- 1 - Question 9

Factorise: 12x + 36

Detailed Solution for Test: Factorisation- 1 - Question 9

Let us take 12 as common
and then the factor is 12(x+3) .

Test: Factorisation- 1 - Question 10

Find the common factors of 2y, 22xy.

Detailed Solution for Test: Factorisation- 1 - Question 10

Only 2y is common in both the terms
