Question

find the solution of 15y-y^2=0

Answer 1

\[\Large\rm 15y-yy=0\]Take a y out of each term,\[\Large\rm y(\qquad ?\qquad)=0\]What are we left with in the brackets? :o
Remember how to factor?

Answer 2

take y common
y(15-y) = 0
so now either y can be zero or 15-y should be zero.
so y = 0, 15

Answer 3

Answer 4

\[15y-y^2=0 \\y(15-y)=0\\y=0 \vee y=15\]
