solving quadratics project
n^2-10n+22=-2
steps to solve the problem..........
1st- make equation equal to zero in this case add 2 to both -2 and 24
2nd- rewrite the problem and get n^2-10n+24=0 then find the gcf so factors of 24 that and up to 10
3rd-then you get 6 and 4 that add up to ten , put them in parentheses and get
(n+6)(n+4)
4th- then take them out of parentheses and make them equal zero and isolate the N so that would look like this- n+6=0 n+4=0, n=6 n=4
5th-then put your answer in brackets ------ {6,4}
Jobs that include Quadratic equations !!!!
Agriculture-they use by finding out the optimal arrangement in boundaries to produce the biggest fields and pens giving the materials on hand,area is the length of a surface multiplied by width,this turns calculations involving areas into quadratic equations.
science-astronomers use quadratic equations to describe the orbits of planets,solar systems and galaxies , chemists need them in order to describe certain types of chemical reactions.
