Question

(x^3-5x^2+3x+1)*(x^2-3)
plz answer fast......its urgent.....​

Answer 1

$(x^{3} - 5x^{2} + 3x+1) ( x^{2} -3)\\\\x^{2} ( x^{3} - 5x^{2} + 3x+1) - 3(x^{3} - 5x^{2} + 3x+1)$

$x^{5} -5x^{4} + 3x^{3}+x^{2} - 3x^{3} + 15x^{2} - 9x-3 \\\\= x^{5} - 5x^{4}+ 3x^{3} - 3x^{3} + x^{2} + 15x^{2} -9x-3\\\\= x^{5} - 5x^{4} + 16x^{2} - 9x -3$
