Question

multiply (x² + 2x + 3) (x² - 3)​

Answer 1

Answer:

$(x^{2} -3)(x^{2} +2x+3)$

Step-by-step explanation:

$(x^{2} + 2x + 3) (x^{2} -3)$

= $x^{4} + 2x^{3} + 3x^{2} - 3x^{2} -6x - 9$

= $x^{4} +2x^{3} - 6x - 9$

= $(x^{4} - 9 )+(2x^{3} -6x)$

= $(x^{2} +3)(x^{2} -3)+2x(x^{2} -3)$

= $(x^{2} -3)(x^{2} +2x+3)$
