Question

Si P(2x-3)= 3x²+4x-2. Halla P(1) + P(3)

ayuda es para hoy

Answer 1

P(2x-3)=3x²+4x-2. Hallar P(1) + P(3)

-> 2x-3=1. ->2x-3=3

2x=4. 2x=6

x=2. x=3

P(2)= 3(2)²+4(2)-2

P(2)=3(4)+8-2

P(2)= 12+8-2

P(2)=20-2=18

P(3)= 3(3)²+4(3)-2

P(3)= 3(9)+12+2

P(3)=27+12-2

P(3)=39-2=37

P(1)+P(3)= 18+37=55

Espero que te ayudo mi solución :)
