Answer 1

Respuesta:

(20x⁵+15x⁷)/5x³+(24x⁷+16x⁹)/-8x⁵ = x²(1+x²)

(20x⁵+15x⁷)/5x³+(24x⁷+16x⁹)/-8x⁵

= (-8x⁵(20x⁵+15x⁷)+5x³(24x⁷+16x⁹))/-(5x³×8x⁵)

= (-160x^(10)-120x^(12)+120x^(10)+80x^(12))/-(40x⁸)

= ( (-160+120)x^(10)+(-120+80)x^(12))/-40x⁸

= ( - 40x^(10) - 40x^(12))/-40x⁸

= (- 40x^(10))/-40x⁸+(-40x^(12))/-40x⁸

= x²+x⁴

= x²(1+x²)
