Factorize Algebraic Expressions

Factorise the expression completely.

Factorise 3x+18.

• 3(x+6)

• 3(x+18)

• 3(x-6)

• 3x(x+6)

Factorise 8m + 32m²n.

• 8(m+4m²n)

• 8m(1+4mn)

• 8m(1+n)

• 4m(2+8mn)

Using cross-multiplication method, what value should be in each box if you need to factorize x² - 6x + 9?

• p=x², q=+6x, r=+9

• p=x², q=+9, r=+6x

• p=x², q=+9, r=-6x

• p=x², q=-6x, r=+9

Factorise ab+bc+pq+pr.

• a(b+c) + p(q+r)

• b(a+c) + p(q+r)

• b(a+b) + p(q+r)

• b(a+c) + q(p+r)

Factorise b² - 81.

• (b-8)(b+8)

• (b-9)(b+9)

• (b-9)(b-9)

• (b-8)(b-8)

Factorize the following expression:

12x-18

• 12(x-3)

• 2(6x-18)

• 6(2x-3)

• -6(2x+3)

Fully factorise the following expression... 4x - 12

• 4(x - 3)

• 2(2x - 6)

• 2(2x - 3)

• 4(x - 12)

Factorize:

x² - 25

• ( x + 5 ) ( x - 5 )

• ( x - 5 ) ( x - 5 )

• ( x + 5 ) ( x + 5 )

• ( x - 25 ) ( x + 25 )

Fully factorize: x² - 4x + 4

• (x + 2)²

• (x - 2)²

• (x + 4)²

• (x - 4)²
