The sum of the polynomial is equal to -10x^3 + 2x^2 + 7x + 8.
what are polynomials?
In mathematics, polynomials refers to an algebraic equation which have more than two terms, the terms are usually same variable but the exponents tends to increase the number of terms.
An algebraic equation with the highest power as two is generally called parabolic equation/ When the power goes above two they are called polynomial.
How to add polynomials
addition of polynomials is achieved by adding like terms together. the like terms as in the question include similar alphabet and same exponents
( -4x^3 + 10x^2 + 6 ) - ( 6x^3 + 8x^2 - 7x - 2 )
terms with x^3: -4 - 6 = -10
terms with x^2: 10 - 8 = 2
terms with x: 0 - ( - 7 ) = 0 + 7 = 7
constant terms : 6 - ( - 2 ) = 6 + 2 = 8
constant terms refers to terms that does not have x
writing the equation together with their terms gives -10x^3 + 2x^2 + 7x + 8. Hence we can conclude that addition of polynomials involves addition performed considering the terms by adding like term.
