Answer 2

Answer:

$\small{\underbrace{\overbrace{{\pink{hello\:dear}}}}}$

Simplify:

a) 40+ (-3a) +c.

solution :

40 - 3a + c

d) 2xy²-7x²y²+9x²y² - 11x²y²

solution :

2 × y² - 9 × ² y²

c) 4x² + y - 7 - 3x²

solution :

x² + y - 7

d) 2l²-2l+4l²-5l

solution :

(21 × 21 )- 21 + (41 × 41) - 51

441 - 21 + 1 , 681 - 51 = 2050

e) a² + b² - 2ab + 2b² - 4ba

solution :

a² - 6ab + b ²
