Question

meee ajudeeeem Resolver Essas equaçoes incopletas::
a)10x2=0
b)x2+6x=0
c)4x2-24x=0
d)x2-81=0
e)3x2-75=0

Answer 1

a)10x²=0
x²= 0/10
x²= 0
x²= √0
x= +/- 0
 b) x²+6x=0
x(x+6)= 0
x=0
x+6=0
x= --6

c)4x²-24x=0
x(4x- 24)=0
x=0
4x-24=0
4x=-24
x=-24/4
x= -6

d)x²-81=0
x²=81
x=√81
x= +/- 9

e) 3x²-81=0 
3x²=81
x²= 81/3
x²= 25
x=√25
x= +/- 5
