How to add polynomials

Add 3x³ -4x² +2x -2 and -2x³ +x² +2x +3

Step 1: Write the polynomials side by side

(3x³ -4x² +2x -2) + (-2x³ +x² +2x +3)

Step 2: Rearrange terms by like degrees

(3x³ + -2x³) + (-4x² + x²) + (2x + 2x) + (-2 + 3)

Step 3: Combine like terms

x³ -3x² +4x +1

How to subtract polynomials

Step 1: Write the polynomials side by side

(3x³ -4x² +2x -2) - (-2x³ +x² +2x +3)

Step 2: Distribute the minus sign to the second polynomial

(3x³ -4x² +2x -2) + (2x³ -x² -2x -3)

Step 3: Rearrange terms by like degrees

(3x³ + 2x³) + (-4x² + -x²) + (2x + -2x) + (-2 + -3)

Step 4: Combine like terms

5x³ -5x² -5
