Question

5. Dados los polinomios:

P= 4x² − 1

Q = x³ − 3x² + 6x − 2
R= 6x² + x + 1
S= 1/2x² + 4
T = 3/2x² + 5
U= x² + 2

Calcular.
a. P + Q
b. R + S
c. U – T
d. R - P

Answer 1

Explicación paso a paso:

1)

$P + Q \\ (4x {}^{2} - 1) + (x {}^{3} - 3 {x}^{2} + 6x - 2) \\ 4x {}^{2} - 1 + {x}^{3} - 3 {x}^{2} + 6x - 2 \\ {x}^{3} + {x}^{2} + 6x - 3$

2,)

$R + S \\ (6 {x}^{2} + x + 1) + ( \frac{1}{2} {x}^{2} + 4) \\ 6 {x}^{2} + \frac{1}{2} x {}^{2} + x + 4 + 1 \\ \\ ( \frac{12 + 1}{2} {x}^{2} ) + x + 5 \\ \\ \frac{13}{2} {x}^{2} + x + 5$

3)

$U -T \\ ( {x}^{2} + 2) - ( \frac{3}{2} x {}^{2} + 5) \\ \\ (x {}^{2} - \frac{3}{2} {x}^{2} ) + 2 - 5 \\ \\ (\frac{2 - 3}{2} x {}^{2} ) - 3 \\ \\ - \frac{1}{2} {x}^{2} - 3$

4)

$R - P \\ (6x {}^{2} + x + 1) - (4x {}^{2} -1 ) \\ 6x {}^{2} - 4 {x}^{2} + x + 1 + 1 \\ 2x {}^{2} + x + 2$

espero que sea de tu ayuda
