Question

Simplify by the following
3a²-4a²b + 7a²- b² - ab​

Answer 1

Answer:

= -1a2 +7a2 -b2-ab

= 6a2-b2-ab

Answer 2

$\sf{\underline{Question}}$

Simplify: $3a²- 4a²b + 7a²- b² - ab$

$\sf{\underline{Solution}}$

First, we combine the like terms:

$⟹ (3a² + 7a²) - (4a²b) - (1ab) - (1b²)$

$\implies{10a² - 4a²b - ab - b²}$

$\implies{10 a × a - 4a × ab- ab - b²}$

$\bold{\red{\implies{10a² - 4a - b²}}}$
