Solve each equation?

Question

x^3 + x^2 = 0

Answer 1

x=-1 or x=0

for anything to add together and equal 0 they have to either cancel or both b zero to begin with  

Answer 2

x^3 + x^2 =0

Factor out an x^2 from each expression...

x^2(x + 1) = 0

By the zero property...

x^2 = 0 OR (x + 1) = 0

Solve these for x to find...

x = 0 OR x = -1

(Be sure to plug these values back in to check)

Answer 3

x^3 + x^2 = 0

[pull out the comon factor of x^2]



x^2(x+1) = 0

[set each term equal zero]

x^2=0   x+1=0

[solve for x]

x=0,         x=-1

Answer 4

x=0 or x=-1

Answer 5

factor out x^2...

x^2(x+1) = 0

x^2=0 OR x= -1

x = 0 or - 1
