Factor the polynomial -3x^4-9x^3+15x^2

3x^2(x^2+3-5) is the answer. i hope this helps:)

We are given

we can rewrite it as

we can see that

each terms are multiple of -3x^2

so, we can factor out -3x^2

now, it can not be factored further

so, we get

oof cheaters cheat because they’re lazy that’s why i cheat xd

step-by-step explanation:

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.
