Question

quien me ayudaa!!... 1)(5a³-6a³+a-5)-(6a²+2a+1+5a²) 2)(2x³+2x-8x²+3)-(4x⁴-6x²+2x-8) 3)(5x²-8x+9)-(x³-x+2) 4)(½p²-¾p²-⅖p)-(⅙p²-¼p)​

Answer 1

Explicación paso a paso:

1).(5a³-6a³+a-5)-(6a²+2a+1+5a²)

$5 {a}^{3} - 6{a}^{3} + a - 5 - 6 {a}^{2} - 2a - 1 - 5 {a}^{2}$

${a}^{3} - 7 {a}^{2} - a - 4$

2)2x³+2x-8x²+3)-(4x⁴-6x²+2x-8)

$- 4 {x}^{4} + 2 {x}^{3} - 2 {x}^{2} + 11$

3). (5x²-8x+9)-(x³-x+2)

$- {x}^{3} + 5 {x}^{2} - 7x + 7$

4).(½p²-¾p²-⅖p)-(⅙p²-¼p)

${p}^{2} ( \frac{1}{2} - \frac{3}{4} - \frac{1}{6} ) - p( \frac{2}{5} + \frac{1}{4} )$
