Dops Factoring

Factor by removing the HCF:

18a²-15a

• 15a(3a-1)

• 3a(6a-1)

• 3(6a-5)

• 3a(6a-5)

Factorise the following:

-9x - 27x²

• -x(9 + 27x)

• -9x(1 + 3x)

• -9(x + 3x²)

• 9x(1 - 3x)

Factorise the following:

(7 - 3x) + x(7-3x)

• x(7 - 3x)

• -3x(7 - x)

• (7 - 3x)(1 + x)

• (7 - 3x)(x)

Factor by grouping:
4p³+8p²+3p+6

• (2p²+3)(p+2)
• (2p²+6)(p+4)
• (4p²+3)(p+2)
• (4p²+8p)(3p+6)

Factor by grouping:
5n³-10n²+3n-6

• (5n²+3)(n-2)
• (5n²-3)(n-2)
• (5n³+3)(n-2)
• 10n(n²-6)

Factor p³ - 3p² - 16p + 48 

• p² ( p - 3) (p - 3) 
• (p² - 16) (p - 3)  
• (p + 4) (p - 4) (p - 3) 

Factorise
x² + 8x 

• (x + 2)(x + 4)
• (x + 8)(x + 1)
• x(x + 8)
• 2x(x + 4)

Factorise fully: ab + 4b

• a(b+4)
• b(a+4)
• ab(1+4)
• b(a+4b)

Factorise 6b + 8

• 4(2b+2)
• 2(3b+4)
• 2(b+4)
• 4(3b+2)

Factorise: 4x² + 8x

• 4x(x+2)
• 4(x²+2x)
• 2x(2x+4)
• 2(2x²+4)
