Expansion of (x + 3y)(x - y) gives(2 Points)
x² + 2xy - 3y²
x + 3y - 2xy
-2y + 3x
3y - 42x
2.Expansion of 2x(x + 2y) + 3x(2x - 3y) yields(2 Points)
8x² - 5xy
8x - 5y
3y - 2y
none of above
3.Expansion and simplification of 8(3h - 4) + 5(h - 2) gives(2 Points)
24h - 37
36 - 4h
29h - 42
38 + 42h
4.: Expansion of -8(3a + 5b) yields(2 Points)
-24a - 40b
-22a + 80b
20a - 30b
-24a - 41b
pls answer fast thank you
