Question

reduza o monômio

1/3 x^2 -2/5 x + 6x + x^2

Answer 1

$\frac{1}{3} x^2 - \frac{2}{5} x + 6x + x^2 = \\ \frac{1}{3} x^2 + {x}^{2} - \frac{2}{5} x + 6x =$

$( \frac{1}{3} + 1) {x}^{2} + ( - \frac{2}{5} + 6)x = \\ ( \frac{1 + 3}{3} ) {x}^{2} + ( \frac{ - 2 + 30}{5} )x =$

$\frac{4}{3} {x}^{2} + ( \frac{ 28}{5} )x =$

$\frac{4}{3} {x}^{2} + \frac{ 28}{5} x$
