Question

Subtract the second expression from the first. (14a² + 8ab + 3b²) ; (26a² - 8ab - 17b²)1piont 12a² + 16ab +20b²
2 point-12a² + 16ab +20b²​

Answer 1

Answer:

From the given equations : — 

3a² - 8ab - 2b² , 3a² - 4ab + 6b²

First Equation : 3a² - 8ab - 2b²

Second Equation : 3a² - 4ab + 6b²

Subtracting second expression from first expression : —

→ 3a² - 8ab - 2b² - ( 3a² - 4ab + 6b² )

→ 3a² - 8ab - 2b² - 3a² + 4ab - 6b²

→ 3a² - 3a² - 8ab + 4ab - 2b² - 6b²

→ - 4ab - 8b²

Therefore, on subtracting the second expression from the second expression we get - 4ab - 8b².
