Question

Multiply: ( 4x² +9) and ( 3x - 2)​

Answer 1

Answer:

$= (4 {x}^{2} + 9)(3x - 2) \\ = 4 {x}^{2} \times 3x \: - 4 {x}^{2} \times 2 + 9 \times 3x \: - 9 \times 2 \\ = 12 {x}^{3} - 8 {x}^{2} + 27x - 18$

Answer 2

Answer:

$( {4x}^{2} + 9)(3x - 2) \\ = ( {4x}^{2} \times 3x) +( {4x}^{2} \times - 2) + (9 \times 3x) + (9 \times - 2) \\ = {12x}^{3} + ( - {8x}^{2} ) + 27x + ( - 18) \\ = {12x}^{3} - {8x}^{2} + 27x - 18$
