If f(x) has a leading term of 3x^4 and zeros at x=2, x=-2, and x= -5, choose all possibly true statements: 3-2 square root of 10 is a zero of f(x) The constant term is 4 x-5 is a factor of f(x) x^2- 4 is a factor of f(x) the sign of f(x) changes twice

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.

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem

hope this
