# Add & Subtract Polynomials Worksheets

How Do You Add and Subtract Polynomials? Polynomials are one of the most significant parts of algebra. Students are aware of linear, quadratic, and cubic equations as they are the most commonly used ones. Any algebraic equations with the exponent on the variable higher than three are termed as polynomials. The polynomials consist of variables, co-efficient, and addition or subtraction operations. Adding and subtracting polynomials is not complicated. All you have to do is put the like terms together and start simplifying it until it cannot be further reduced or simplified. Example: Add 3x4 + 2x + 4x2 -10 + 5x3 and 10x3 + 5x - 2x2 +4 To add these two polynomials, you have to write it down in the form of a sum; x4 + 2x + 4x2 -10 + 5x3 + (10x3 + 5x - 2x2+4) Start arranging the terms in a way that the exponent on the variables in descending order. x4 +5x3 + 10x3 + 4x2 - 2x2 + 2x + 5x - 10 + 4 Now you see, by placing the values in a way that the exponents are in descending order, you have gathered the like terms together. x4 +15x3 +2x2 + 7x - 6
