A ball is hit vertically into the air using a paddle at a speed of 32 ft/sec. The expression -16t^2 + 32t give the ball's height after t seconds. Factor this expression.

-16t (t-2)

Step-by-step explanation:

−16t² + 32t = 256t² + 32t

Factor out the GCF:

-16t (t-2)

-16t(t - 2).

Step-by-step explanation:

-16t^2 + 32t    The GCF is -16t so we have:

-16t(t - 2).

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,                                                                    

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
