Answer 1

I hope this is ur answer

Answer 2

Given,

The given algebraic term for simplification is = (a-2b+5c)(a-b)-(a-b-c)(2a+3c)+(6a+b)(2c-3a-5b)

To find,

The final result of the simplification of the given algebraic term.

Solution,

We can easily solve this mathematical problem by using the following mathematical process.

We just need to do algebra addition multiplication subtraction etc, to simplify the given algebraic term.

Simplification :

(a-2b+5c)(a-b)-(a-b-c)(2a+3c)+(6a+b)(2c-3a-5b)

= (a²-2ab+5ac-ab+2b²-5bc)-(2a²-2ab-2ac+3ac-3bc-3c²)+(12ac-18a²-30ab+2bc-3ab-5b²)

= a²-2ab+5ac-ab+2b²-5bc-2a²+2ab+2ac-3ac+3bc+3c²+12ac-18a²-30ab+2bc-3ab-5b²

= 3c²-19a²-3b²+16ac-34ab

Hence, the final answer will be 3c²-19a²-3b²+16ac-34ab
