Question

Simplifique, reduzindo os termos semelhantes a) P+P+5P B) 2a- 1 + 7a -6 c)x+6-6x+9-7x D) x^2-5y+8x^2+ 1+10y

Answer 1

a)
= P+P+5P
= 2p + 5p
= 7p

B)
= 2a - 1 + 7a - 6
= 2a + 7a - 1 - 6
= 9a - 7

c)
= x + 6 - 6x + 9 - 7x
= x - 6x - 7x + 6 + 9
= x - 13x + 15
= - 12x + 15

D)
= x^2 - 5y + 8x^2 + 1 + 10y
= 8x^2 + x^2 - 5y + 10y + 1
= 9x^2 + 5y + 1
