Its quick i just need with this one that im stuck on

discriminent worksheet

a: -4 ex: -4m^2-3m+3=-6
+6 +6

b: -3

c: 9 .

-4m-3m+9=0

b^2-4ac

(-3)^2-4(-4)(9)

9+144

153

(i need this one solved with the work shown)

2.) -4k^2-4k+6=-4

what the question so we can you out

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

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.
