Question

a) $4x^{2} -12xy+5y^{2}$
b)y²+22y+121
c) 81p²-18p+1
d) 4b²+16+6x²
e)a3-1
f)x³+8
g)27-m³

socorrooooooooooooo

Answer 1

a) 4x^2-12xy+5y^2−12xy+5y2 

4x^2-24xy+y^2


b)y²+22y+121

∆=484-4.121

∆=0

x1=x2=-22/2

x1=x2=-11

c) 81p²-18p+1

∆=324-4.81

∆=0

x1=x2=18/162=1/9



d) 4b²+16+6x²
(sem solucão)


e)a3-1 

a=-1

f)x³+8

x=-2



g)27-m³

m^3=27

m=3 ou m=-3

Answer 2

Eu sei algumas.

e) a= 1/3

f) x= (-2)

g) m = 3
