Sumar polinomios?................ ​

Answer 1

Explicación paso a paso:

$p1 = 5x^{3} + 4x - 3 \\ p2 = 7x^{4} - 2x ^{2} + x - 2 \\ p3 = 6 {x}^{2} - 3x + 5 \\ \\ p2 + p3 \\ \\ (7 {x}^{4} + 0 {x}^{3} - 2 {x}^{2} + x - 2) + (6 {x}^{2} - 3x + 5) \\ 7 {x}^{4} + 0 {x}^{3} - 2 {x}^{2} + x - 2 + 6 {x}^{2} - 3x + 5 \\ \\ = 7 {x}^{4} + 0 {x}^{3} + 4 {x}^{2} - 2x - 3$

$p1 + p3 \\ \\ (5x^{3} + 4x - 3) + (6 {x}^{2} - 3x + 5) \\ \\ 5 {x}^{3} + 0 {x}^{2} + 4x - 3 + 6 {x}^{2} - 3x + 5 \\ \\ = 5 {x}^{3} + 6 {x}^{2} + x + 2$
