Find a possible expression for a quadratic function with zeros - 5 and 0

Your zeros =

x = - 5

x = 0

make the two functions equal zero.

1:

x = - 5

add 5 to both sides

x + 5 = 0

2:

x = 0

now that you have found your two functions, simply multiply them:

x (x + 5) = x^2 + 5x

your solution:

y = x^2 + 5x
