$(\frac{7}{4} x^{3} +\frac{6}{5} x^{2} )-(-\frac{3}{8} x^{3} -3x^{2} )=\frac{85x^{3}+168x^{2} }{40} \\\\pasos:\\\\(\frac{7}{4} x^{3} +\frac{6}{5} x^{2} )-(-\frac{3}{8} x^{3} -3x^{2} )\\\\Quitar-los-parentesis:(a)=a\\\\\frac{7}{4} x^{3} +\frac{6}{5} x^{2} -(-\frac{3}{8} x^{3} -3x^{2} )\\\\-(-\frac{3}{8} x^{3} -3x^{2} ):\frac{3x^{3} }{8} +3x^{2} \\\\simplificar>\frac{7x^{3} }{4} +\frac{x}{y} +\frac{x}{y} +3x^{2} :\frac{85x^{3}+168x^{2} }{40} \\\\solucion:\\\\=\frac{85x^{3}+168x^{2} }{40}$
