Create your own quadratic equation and demonstrate how it would be solved by graphing, factoring, the quadratic formula, and by completing the square.
give me a quadratic formula and ill try to walk you through it
equation I mean
Theres the part Im having trouble with, im not very good at making one up, i can probably solve it after I have one.
alright. lets make it an easy one \[x^2+5x+6\] do you know what makes this quadratic?
=0
ummm, no.
Can you help solve it by graphing thats the only one I dont know how to do.
alright the degree tells you its quadratic \[x\] is linear \[x^2\] is quadratic \[x^3\] is cubic now how do you solve this by factoring.
make a t table|dw:1385256930160:dw|
okay
once you get your ordered pairs from the t table just plot them and fill in the parabola
how do I get the ordered pairs?
the x values you make up and when you plug x in to the quadratic equation your y value is the answer consider \[f(x)=x^2+5x+6\] where f(x)=y so you plug x values in to find y if you plug 0 in for x you get the ordered pair (0,6)
when I was in high school we were taught to just generically use -2,-1,0,1,2 for your x values to solve for the corresponding y values then graph it
