Question

Efetue as operações:
a) (y2 + 4y – 5) + (– 3y2 + 12y – 1).
.b) (2 x 3 + 5 x 2 + 4 x) − (2 x 3 − 3 x 2 + x )
c) (3 x 3 - 2 x 2 ) . (x 3 − 3 x 2)
d) ( 18y5 + 24y4 – 15y2) : (– 3y2).

Answer 1

Resposta:

12y-6 b 16+3x c15x-30 d -26

Explicação passo a passo:

(y2 + 4y – 5) + (– 3y2 + 12y – 1)

(2y+4y-5)+(-6y+12y-1)

(6y-5)+(6y-1)

6y-5+6y-1

(2 x 3 + 5 x 2 + 4 x) − (2 x 3 − 3 x 2 + x )

(6+10+4x)-x

(16+4x)-x

16+4x-x

(3 x 3 - 2 x 2 ) . (x 3 − 3 x 2)

(9-4)x (3x-6)

5(3x-6)

( 18y5 + 24y4 – 15y2) : (– 3y2)

(90y+96y-30y)/(-6y)

156y/(-6y)
