Porfavor ayuda con estos 3 puntos álgebra

Answer 1

Respuesta:

Explicación:

7x^2 - (1/2)x^2 - (5/2)x^2 + 2x^2 - (3/2)x^2

= 7x^2 + 2x^2- (1/2)x^2 - (5/2)x^2 - (3/2)x^2

= 9x^2 + (- 1 - 5 - 3)x2/2

= 9x^2 - (9/2(x^2

= (18 - 9)x^2/2

= 9/2x^2

- v + v^2 + v^3 + 3v^2 - 2v^3 + 2v + 3v^3

= 3v^3 + v^3 - 2v^3 + v^2  + 3v^2 - v + 2v

= 2v^3 + 4v^2 + v

= v(2v^2 + 4v + 1)

= v((2v^2 + 4v) + 1)

= v((2v(v + 2)) + 1)

2a^3b + 5a^2b - (2/3)a^2b - a^2b + (1/2)a^2b

= 2a^3b + (5 - (2/3) - 1 + (1/2))a^2b

= 2a^3b + a^2b(30 - 4 - 6 + 3)/6

= 2a^3b + a^2b(23/6)

= a^2b(2a + (23/6))
