Question

gente me salva! tem que responder rápido!

1- simplifique as expressões

a- (2x+1)2 + (3x+1)2 (gente é ao quadrado esses dois)
b-5x-(2x+3)
c-(x+5)2 - x (x+3)
2-simplifique as expressões
a- (x-4)2 - (x-1)
b-(x+1)2- (x-2)
c-(2x-1)2 + x (3x - 2)
d- x (x-1)2 + 2(x+3)

Answer 1

1) a) (2x+1)^2 + (3x+1)^2

4x+1 + 9x+1

13x+2

b)5x-(2x+3)

5x-2x-3

3x-3

c)(x+5)2 - x (x+3)

x+5*2-2x-3x

x +10-2x-3x

10-4x

2) a)(x-4)2 - (x-1)

x-4 *2 -x+1

x-8-x+1

0x -7

b-(x+1)2- (x-2)

x+1*2-x+2

x+2-x+2

0x+4

c-(2x-1)2 + x (3x - 2)

2x-1*2+3x-2x

2x-2+3x-2x

-2+3x

d- x (x-1)2 + 2(x+3)

x-x*2+2x+6

x-2x+2x+6

x+6
