Respuesta:
a. P(x)+ L(x)=
(3x2-5x+1) +(x2-7x-3)
3X2-5X+1+X2-7X-3=
4X2-12X-2
b. P(x)-L(x)=
(3x2-5x+1)-(x2-7x-3)=
3X2-5X+1-X2+7X+3=
2X2+2X+4
Explicación paso a paso:
a. P(x) + Q(x)=
(7x2 – 5x4 +3x – 15)+(5x3 – 7 + 9x2 – 6x)
-5X4+7X2+3X-15+5X3+9X2-6X-7=
-5X4+5X3+16X2-3X-22
b. P(x) - Q(x)=
(7x2 – 5x4 +3x – 15)-(5x3 – 7 + 9x2 – 6x)
7x2 – 5x4 +3x – 15-5x3 + 7 -9x2 + 6x
-5X4-5X3-2X2+9X-8
