NONSENSE = REPORT
E, Learning Task 2: Find the Product.
1. (a + 5)²
2. (3xy - 7)²
3. [x + (y —2)]² = x²(y-2)²
4. (2x + 3y + 5)²= =4x²+12xy+9y²+20x+30y+25
5. (3a - b + 2c)²= 9a²−6ab+12ac+b²−4bc+4c²
6. (4 - 2x)(4 + 2x)= −4x²+16
7. (3xy - abc)(3xy + abc)= −a2b2c2+9x2y2 or abc²9x²y²
8. (x² + 4y²) (x² - 4y²)= x⁴−16y⁴
9. [2 + (x - 1)][2 - (x — 1)]=2x²(x-2)²
10. [(x + 2) - (y + 1)][x + 2) + (y + 1)]= x2−xy+3x−y+3
11. (2 + 2x)³= 8x³+24x²+24x+8
12. (x² - 3)³= x6−9x4+27x2−27
13. (2x + 5)³= 8x³+60x²+150x+125
14. [(x + 1) - y]³= x³−3x²y+3xy²−y³+3x²−6xy
15. [x + (y - 2)]³= x³+3x²y+3xy²+y³−6x²−12xy−6y2+12x+12y−8
