Directions: Find the sum of 11x² -3x + 8 and -5x² + 4x - 13​.

Answer: 6x²+x-5

Solution:

= (11x² -3x + 8) + (-5x²+4x-13)

= 11x²-3x+8-5x²+4x-13

= 11x²-5x²-3x+4x+8-13

= 11x²-5x²-3x+4x-5

= 6x²-3x+4x-5

= 6x²+x-5

 

Remember: This polynomial is a sum of some powers of a specific variable, with the some factor to multiply each power. If this condition exists, adding two polynomials essentially means combining the coefficients of the same powers.
