a penguin leaps out of the water while swimming. The height y (in feet) of a proposing penguin can be modeled by y= -16x2 + 20x where x is the time (in seconds) since the penguin leaps out of the water. find the root of the equation when y = 0

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,
