Distribute each and each time era of one ingredient into the different ingredient. (4x + 2)(7x^2 + 5x + 3) = 4x((7x^2 + 5x + 3) + 2(7x^2 + 5x + 3) = 4x(7x^2) + 4x(5x) + 4x(3) + 2(7x^2) +2(5x) + 2(3) = 28x^3 + 20x^2 + 12x + 14x^2 + 10x + 6 = 28x^3 + 20x^2 + 14x^2 + 12x + 10x + 6 = 28x^3 + 34x^2 + 22x + 6

3(4x+6)+7x
expand the brackets
12x + 18 + 7x
19x + 18

3(4x + 6) + 7x
= 3*4x + 3*6 + 7x
= 12x + 18 + 7x
= 12x + 7x + 18
= 19x + 18
