1. Expansion of (x + 3y)(x - y) gives x² + 2xy - 3y² x + 3y - 2xy -2y + 3x 3y - 42x 2.Expansion of 2x(x + 2y) + 3x(2x - 3y) yields 8x² - 5xy 8x - 5y 3y - 2y none of above 3. Expansion and simplification of 8(3h - 4) + 5(h - 2) gives 24h - 37 36 - 4h 29h - 42 38 + 42h 4.Expansion of -8(3a + 5b) yields -24a - 40b -22a + 80b 20a - 30b -24a - 41b pls kindly ANSWER ALL Share with your friends Share 0 Anikesh Kumar Mishra answered this 1 View Full Answer
