I'm solving a quadratic equation which is 2x^2-x-10=0 and I know that a=2 b=-1 and c=-10 ans with the problem put it into the formula which is -(-10 +- √ -1^2-4(2)(-10) and when I get my answer...
i need help understanding this question. i need the answer and i need the work to be shown so i could fully understand.
if e + h = 5g and e + 5g + h = 40, what is the value of g?
I don't know how to do this without graphing it. Is there any other way?
2x^2 + 4x + 4 = 0
I just need to know how to use the quadratic formula so I can begin to understand it in a better and easier way.
The problem I got was x2-2x+26=0 and the answer ended up being [1+5i,1-5i]. I don't understand how it up being that.
can i get help in solving this. the question is: solve by using quadramatic formula: 3p2 + 7p + 4 = 0 how do i figure this...
how do I get the answer
can be approximated by the model P=0.1220t^2 + 1.529t + 18.72, 7 <= t <=14, where t represents the year, with t=7 corresponding to 1997. a) determine algebraically when the average...
