Math simplify (7a+5b-2c) + (5a+7b) + (2a-7c) + (2a-5b+3c) algebra

Alekssandra [29.7K]

Answer:

$-10a^2+25ab-15ac+12a+12b-2c$

Step-by-step explanation:

$(7a+5b-2c)+(5a+7b)+(2a-7c)+(2a-5b+3c)$

Distribute:

$=7a+5b-2c+5a+7b+(2a)(2a)+(2a)(-5)+(2a)(3c)+(-7a)(2a)+(-7a)(-5b)+(-7a)(3c)$

$=7a+5b-2c+5a+7b+4a^2-10ab+6ac-10a^2+35ab-21ac$

Combine all like terms:

$=(4a^2-14a^2)+(-10ab+35ab)+(6ac-21ac)+(7a+5a)+(5b+7b)+(-2c)$

$=-10a^2+25ab-15ac+12a+12b-2c$
