Step-by-step explanation:
Q1) Add:
1) (8a² - 5ab + 3b²) + ( 2ab - 6b² + 3a²) +
( b² + ab - 6a²)
= 8a² - 5ab + 3b² + 2ab - 6b² + 3a² + b² + ab - 6a²
= 8a² + 3a² - 6a² - 5ab + 2ab + ab + 3b² - 6b² + b²
= 5a² - 2ab - 2b². ANS.
Sorry! but it's very big.. I am giving you the Example that how to do it.
so, A, B, C and E will be done like this...
Q2) Subtract:
1) ( 6x⁴ - 4x³ - 8x² - 2x + 7) -
(7x⁴ - 5x³ + 4x² + 3x - 3)
= 6x⁴ - 4x³ - 8x² - 2x + 7 - 7x⁴ + 5x³ - 4x² - 3x + 3
= 6x⁴ - 7x⁴ - 4x³ + 5x³ - 8x² - 4x² - 2x - 3x + 7 + 3
= - 1x⁴ + 1x³ - 12x² - 5x + 10 ANS.
Sorry! but I know this much....
In subtract, The no. after "from" should be written in first....
I hope it helps you ✌️..
