who is Cree do we learn how to graph quadratic equations now all quadratic equations can be shown as progress 19 X Y graph and you only need three points to graph a quadratic equation but 5 Galaxy 3  is recommended to do or two x intercepts  and Now directions to shots are pretty easy to find Sense on the x-axis why is always zero reset what is zero and root at two solutions which will be the value of the two something to fight everything by 5 since everything is by here and get Square  -10x / 16 is cereal how to factor disc we need something that multiplies something that would be 16 and 2 things out to be -10 and -2 with work since -2 times -8 would be 16 + -8 + -2 would be -10 X -8 X thanks to choo choo X values would be if x equals XY  set this would be to zero and the y-axis will be right here eight zero not find a Vertex we can use a formula the inverse of the  HOA so if a standard form quadratic equation with the ax squared flash C equals why can a would be 5 + b 14 solve 50 / 2 * 5  which conceive would be since * 5 is 1050 / 10 V5 so here  the x value of the 5 it's like five in 4X and we solve air condition and subtracting numbers in -45  when you call Snow White value of the vertex mean -45 check out work on a graphing calculator  if the input in here we can see 3.3 crafts for 20805 the answers correct  Jennifer hit a golf ball in the ground and fall of the projectile hot equals negative 16t squared plus 100 tea party is time seconds and each side of the ball find soccer golf ball reach-in also and hits the ground again find the reasonable domain and range for the situation what's a pleasure equation is age of tea  equals -60 in chi-square first 100 c and ask for  the highest point that are beached and also one hit the ground again Telegraph  said that she hit the golf ball in the ground today the heights would be 0 and  so be something like this what does 00  the right now we're trying to find  are there X and the vertex so again find the X intercepts where why would be 0 replace each of teeth with zero 0 equals negative 16t squared flash 102 weather in sirvaitis entire question by -4  because we want to get rid of the negative in front of the shiro-4 P-Square -25 t how can factor out a cheat  we can get zero doesn't count / TM go to site from here so be 0 equals  tee times  40 -25  which pretty clear Ellen DeGeneres v0t if zero then OB 0  so we want to find out how to make the sign of the  design 0 show me 201 to 4325 to cancel on that 25 before 25  survival sites by 4 she would be 6.25 so this is 0-0 this 6.25 0 now all we have left fine is the vertex find a Vertex we can again use a formula inverse of you to a button-down mean 100 are you too son easier way to do this find the mean of the X values of the two x intercepts  ashta vertex play right in between so 6.25 + 0 would be 6.25 / 2  movie 3 and quarter or 3.125  so if you can either we can do I have to plug this number into here  and so why was the -16  now is she use the fraction form of 3.125 Obe Square 3 and 1/4 1/8 Square + 100 time play Learn to Fly don't have simplified we should turn me and 1/8 into an improper fraction which would be 25 / 8 square and just wants chicken Ruby 3 / 12.5 now we have to square 25/8 Square both sides of fraction in numerator and the denominator 25 squared 625 each square is 64 can we just leave the 12.5 now we can cross cancel this so negative 16 -1 how to make S4 this will be -325 over 4 + negative so 625 / -625 / 4 would be -1 56.25 add you champ the numbers into a calculator and why would be 156 life  which means starts dis  I want to 5625 is half of 312.5 so this would be 3.4 - 5 and 156 way too far search 3.003 - 556.25 Desmos Hero Zero I'm 6.25 answers for p 3.125 which is exactly what are three points answer is correct
