Question

1.Multiply:
i) 2ab by -2ab
ii)³/2 ab² by -⅔ a²b
iii)-3 x² by ⁴/3 x⁴
iv)½ xy by-⅗ x³y³
v)-2 x by (2 x² + y² + 4 xy)
vi) (x² + 4 x - 1) by (x + 1)

2.Multiply:
i)(2 x² - 2 xy + 4 y²-2) by 2 xy
ii)(4 x³ - 4 x² +7) by (x² - 1)
iii) 6 x⁴ - 3 x² + 4 x² - 2 x+1) by -5x

3.Simplify the following:
i)(2 x +3) (x-4)
ii)(3 x -7) (4 x+3)
iii) (ax + b) (c +dx)
