Y=-x^2
Y=x
Please help got to do today

Answer 1

x= o and -1

Answer 2

How did you get that

Answer 3

we have y=x=-x^2

Answer 4

or simply x=-x^2

Answer 5

shift everything to LHS,
so x^2 +x=0

Answer 6

take x common
so the equation is x(x+1)=0
now the product of two numbers( x nd (x+1)) is 0, so either one of them can be equal to 0

Answer 7

so this implies either x=0 or x+1=0
solving both we get x= 0 and -1
