Expand 3(4y + 1)

• 12y + 3
• 12y + 1
• 13y
• 3y

Expand and simplify 4(m + 3) + 3 (2m -5)

• 4m + 12 + 6m + 15
• 10m + 27
• 4m + 12 + 6m - 15
• 10m - 3

Expand s(s² + 6)

• s² + 6s

• s³ + 6

• s³ + 6s

• 6s³

Expand (x + 8) (x - 2)

• x² + 6x - 16
• x² + 10x + 6
• x² + 6x + 10
• x² - 6x - 16

Expand and simplify 4(2x - 1) + 3(x + 6)

• 8x - 4 + 3x + 18
• 11x + 2
• 11x - 2

Factorise 4c + 12

• 4 (c + 12)
• 2 (2c + 6)
• 4 (c + 3)

Expand and simplify (x + 2)(x - 2)

• x² + 2x + 4
• x² + 4
• x² + 2x - 2x - 4
• x² - 4

Factorise completely 12y² - 8y

• 2 (6y² - 8)

• 2y (6y - 2)

• 4y (3y² - 2)

• 4y (3y - 2)

Factorise

y² + 4y + 4

• y+2y-2
• (y + 2)(y + 2)
• (y + 4)(y + 1)
• (y - 2)(y - 2)

x + 4 = y

Make x the subject.

• x = y + 4

• x = y - 4

• x = y ÷ 4

• x = y × 4
