Question

por favor lo tengo que entregar hoy !!​

Answer 1

a) (2x-3)*(4x+2)= $8x^{2} +4x-12x-6$ = $8x^{2} -8x-6$

b) $(3x-1)*(2x^{2} -8x+3)$ = $6x^{3} -24x^{2} +9x-2x^{2} +8x-3$ = $6x^{3} -26x^{2} +17x-3$

c) $(-x-1)*(-x^{2} -5x+3)$ = $x^{3} +6x-3x+x^{2} +5x^{2} -3$= $x^{3} +6x^{2} +2x-3$

d) $(18x^{5} -8x^{4} +6x^{2} )/(-2x)$ = $-9x^{4} +4x^{3} -3x$

e) $(24x^{6} +9x^{4} -6x^{2} )/(3x^{2} )$ = $8x^{4} +3x^{2} -2$
