Question

multiply (4x² - x +2) (x² + 3x +5) ​

Answer 1

$(4 {x}^{2} - x + 2)( {x}^{2} + 3x + 5) \\ \\ = > 4 {x}^{4} + 12 {x}^{3} + 20 {x}^{2} - {x}^{3} - 3 {x}^{2} - 5x + 2 {x}^{2} + 6x + 10 \\ \\ = > 4 {x}^{4} + 12 {x}^{3} - {x}^{3} + 20 {x}^{2} - 3 {x}^{2} + 2 {x}^{2} - 5x + 6x + 10 \\ \\ = > 4 {x}^{4} + 11 {x}^{3} + 19 {x}^{2} + x + 10$
