Which functions have real zeros at 1 and 4? Check all that apply.
f(x) = x2 + x +4
f(x) = x2 - 5x + 4
f(x) = x2 + 3x - 4
f(x) = -2x2 + 10x - 8
f(x) = -4x2 - 16x-1

Complex numbers multiply √-4 * √-25 and show all intermediate steps. alternative notation is sqrt(-4) * sqrt(-25).

Define multiplicative inverse. give an example of a number and its multiplicative inverse.
