Factor the trinomial -2h^2+5h+3

-2h²+5h+3=-(2h+1)(h-3)

Step-by-step explanation:

-2h²+5h+3=0

Delta=5²-4×(-2)×3=25+24=49=7²

h1=(-5+7)/(-4)=2/(-4)=-1/2

h2=(-5-7)/(-4)=-12/(-4)=12/4=3

Finally

-2h²+5h+3=-2(h+1/2)(h-3)=-(2h+1)(h-3)

the answer is two. hope this !

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
