Multiplying polynominals

Question

(3x+7) (x-8)

Answer 1

(3x)(x) + 7x - 8(3x) + (7)(-8) FOIL form Algebra 1.

Answer 2

(3x+7)(x-8)

= 3x^2 +7x -24x- 56

= 3x^2 - 17x -56

Answer 3

Given that the polynomials are (3x+7)(x-8).

Multiplying these polynomials to find its equation.

(3x+7)(x-8)=3x×x-3x×8+7×x-8×7

(3x+7)(x-8)=3x²-24x+7x-56

(3x+7)(x-8)=3x²-17x-56

Multiplying the polynomials (3x+7)(x-8) the obtained equation is 3x²-17x-56.
