Question

considera los polinomios A,B y C y calcula A+B y B-C​​

Answer 1

Respuesta:

A+B=

(5 {x}^{2} + 2x - 9) + (5 {x}^{4} - 3 {x}^{3} + 4 {x}^{2} + 6x - 7)(5x2+2x−9)+(5x4−3x3+4x2+6x−7)

5 {x}^{2} + 2x - 9 + 5 {x}^{4} - 3 {x}^{3} + 4 {x}^{2} + 6x - 75x2+2x−9+5x4−3x3+4x2+6x−7

5 {x}^{4} - 3 {x}^{3} + 9 {x}^{2} + 8x - 165x4−3x3+9x2+8x−16

B-C=

(5 {x}^{4} - 3 {x}^{3} + 4 {x}^{2} + 6x - 7) - (6 {x}^{3} + 4 {x}^{2} - x + 7)(5x4−3x3+4x2+6x−7)−(6x3+4x2−x+7)

5 {x}^{4} - 3 {x}^{3} + 4 {x}^{2} + 6x - 7 - 6 {x}^{3} - 4 {x}^{2} + x - 75x4−3x3+4x2+6x−7−6x3−4x2+x−7

5 {x}^{4} - 9 {x}^{3} + 7x5x4−9x3+7x

Answer 2

Respuesta:

A+B=

(5 {x}^{2} + 2x - 9) + (5 {x}^{4} - 3 {x}^{3} + 4 {x}^{2} + 6x - 7)(5x2+2x−9)+(5x4−3x3+4x2+6x−7)

5 {x}^{2} + 2x - 9 + 5 {x}^{4} - 3 {x}^{3} + 4 {x}^{2} + 6x - 75x2+2x−9+5x4−3x3+4x2+6x−7

5 {x}^{4} - 3 {x}^{3} + 9 {x}^{2} + 8x - 165x4−3x3+9x2+8x−16

B-C=

(5 {x}^{4} - 3 {x}^{3} + 4 {x}^{2} + 6x - 7) - (6 {x}^{3} + 4 {x}^{2} - x + 7)(5x4−3x3+4x2+6x−7)−(6x3+4x2−x+7)

5 {x}^{4} - 3 {x}^{3} + 4 {x}^{2} + 6x - 7 - 6 {x}^{3} - 4 {x}^{2} + x - 75x4−3x3+4x2+6x−7−6x3−4x2+x−7

5 {x}^{4} - 9 {x}^{3} + 7x5x4−9x3+7x
