Question

sendo:
A= x +1
B= x² +2
C= 2x-3
D=x² + 2x + 4

caucule:
a) A.B
b)A.C
c)A.D
d)B.C
e)B.D
f)C.D​

Answer 1

a) A.B = (x+1)(x²+2) = x³+2x+x²+2 = x³+x²+2x+2

b) A.C = (x+1)(2x-3) = 2x²-3x+2x-3 = 2x²-x-3

c) A.D = (x+1)(x²+2x+4) = x³+2x²+4x+x²+2x+4

x³+3x²+6x+4

d) B.C = (x²+2)(2x-3) = 2x³-3x²+4x-6

e) B.D = (x²+2)(x²+2x+4) = x⁴+2x³+4x²+2x²+4x+8

x⁴+2x³+6x²+4x+8

f) C.D = (2x-3)(x²+2x+4) = 2x³+4x²+8x-3x²-6x-12

2x³+x²+2x-12
