Accepted inputs: A2: -100 to 100 number; A1: -100 to 100 number; A0: -100 to 100 number; B2: -100 to 100 number; B1: -100 to 100 number; B0: -100 to 100 number; Coefficient: choose Constant coefficient (0), x coefficient (1), x² coefficient (2).
How the calculation works
[x^k](P+Q)=ak+bk
Collect equal powers of x when adding two quadratic polynomials.
Worked example
With a2 2 number, a1 3 number, a0 4 number, b2 5 number, b1 6 number, b0 7 number, coefficient x² coefficient, sum of two quadratics coefficient is 7 number.
