What is the sum of the polynomials?

(6x+7+x^2) + (2x^2-3)

A polynomial is a combination of terms separated by + + or - - signs. A polynomial does not contain variables raised to negative or fractional exponents, variables in the denominator or under a radical, or any special features such as trigonometric functions, or logarithms. Polynomial

Hai!

6x+7+x^2+2x^2-3

6x+7+x^2+2x^2+-3

combine like terms

6x+7+x^2+2x^2+-3

(x^2+2x^2) + (6x) + (7+-3)

=3x^2+6x+4
