Question

1)
P(x)= 3x2-5x
Q(x)= x-3
R(x)=x2-x+1

2)
a) P(x)+Q(x) +R(x)=

b) P(x).Q(x)=

3)
a) -3x+4= 2x -1

b) 5(x-2)= 2x +1

Answer 1

Explicación paso a paso:

a)

$3{x}^{2} - 5x + (x - 3) + ( {x}^{2} - x + 1$

$3 {x}^{2} - 5x + x - 3 + {x}^{2} - x + 1$

$3 {x}^{2} + {x}^{2} - 5x + x - x - 3 + 1$

$4 {x}^{2} - 5x - 2$

B)
