In dividing 2 Quadratics (eg. x^2+5x+4 and x^2+4x+3 (not these , these are just examples ) my friend pointed out that if you remove the squared on the x and and the 4x (e. g) and keep the final to make (x+4)/(x+3). And then find the highest common factor in them (3 and 4) then divide them by it (in this example its one) so the final answer is (x+4)/(x+3). How can you prove this is wrong/correct?

answer

the correct answer is

explanation

the given function is

the excluded values are obtained by solving:

we factor to obtain:

the excluded values are

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.

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things
