Question

X(x+5)²+2x³-4x²=3x(1+x)²+22 con desarrollo plis❤

Answer 1

$x {(x + 5)}^{2} + 2 {x}^{3} - 4 {x}^{2} = 3x {(1 + x)}^{2} + 22 \\ x( {x}^{2} + 10x + 25)+ 2 {x}^{3} - 4 {x}^{2} = 3x(1 + 2x + {x}^{2}) + 22 \\ {x}^{3} + 10 {x}^{2} + 25x + 2 {x}^{3} - 4 {x}^{2} = 3x + 6 {x}^{2} + 3 {x}^{3} + 22 \\ 3 {x}^{3} + 6 {x}^{2} + 25x = 3 {x}^{3} + 6 {x}^{2} + 3x + 22 \\ 25x = 3x + 22 \\ 25x - 3x = 22 \\ 22x = 22 \\ x = \frac{22}{22} = 1$

Listo, saludos.
