Answer 2

Question

• Add (3x²-x+5) + (2x³+x-3) -- (1)
• Subtract (1) by 3x²+2

Solution

• (3x²-7x+5) + (2x³+x-3)

• 2x³+3x²-6x+2

Now, diminish 2x³+3x²-6x+2 by 3x²+2

• 2x³+3x²-6x+2
•      -3x² -    -2  (sign reverses in subtraction)

     ____________

• 2x³-6x      

∴ The final result is 2x³-6x
