P(x): 149x⁶-89x²+70x⁹-55x³+240x-14
S(x): 89x⁵-46x²+63x-39x³-21x⁶+89x⁴

Calcular R(x) - Q(x):
R(x): 251x⁶+27x⁸-26x²+54x-75x⁵-23
Q(x): 21x⁵-74x⁶-81x³-78x-14x²+92

Answer 1

Explicación paso a paso:

$P_{(x)} + S_{(x)} =70 {x}^{9} + (149 - 21) {x}^{6} + 89 {x}^{5} \\+ 89 {x}^{4} + ( - 55 - 39) {x}^{3} + ( - 89 - 46) {x}^{2} \\ + (240 + 63)x + ( - 14) \\ \\ P_{(x)} + S_{(x)} =70 {x}^{9} + 128{x}^{6} + 89 {x}^{5} + 89 {x}^{4} \\ - 94 {x}^{3} - 135 {x}^{2} + 303 x - 14$

$R_{(x)}-Q_{(x)} = 27 {x}^{8} + (251 + 74) {x}^{6} \\ + (- 75 - 21) {x}^{5} - ( - 81) {x}^{3} + ( - 26 + 14) {x}^{2} \\ + (54 + 78)x + ( - 23 - 92) \\ R_{(x)}-Q_{(x)} = 27 {x}^{8} + 325 {x}^{6} - 96 {x}^{5} + 81 {x}^{3} \\ - 12 {x}^{2} + 132x - 115$
