Multiply out the brackets. Which result is correct?
(x + 2y)(3x + 2y)
Expand
(3x − 8)(7x − 11)
Divide (x ≠ 0, x ≠ 1)
[(x² − 2x + 1)/(4x)] : [(x − 1)/(8x²)]
Take the common factor out of the bracket
72x³ + 81x²
Expand
(4x² + 7x + 2)(5x − 3)
Factorise
36x² − 289
Calculate
56 · 64
Expand
(9x − 7)(9x + 7)
Carry out the operation
(5x³ − 5x² − 9x + 8) − (3x³ + 6x² − 8x + 9)
Expand
(6x − 2)²
