Question

what is y squared subtract 10y equal negative 9

Answer 1

\[^{y2}-10y =-9\]

Answer 2

y=-1,y=9

Answer 3

can you show me how to break it down

Answer 4

Dipin probably factored the expression by first rearranging the expression to read:
y^2-10y+9=0 (adding 9 to both sides)
(y-9) (y-1)=0 (factoring) Now if these products equal zero, the one or both of the products equal zero.

x-9=0 then x=9
x-1=0 then x=1
It appears that dipin may have lost track of his signs.
